Speed

Opera was always a very fast browser and while we didn't perform any formal benchmark tests yet, the latest version feels just as fast (if not even a bit faster) than Google Chrome. The current alpha version doesn't include support for hardware acceleration yet, but Opera plans to enable this feature before launching the final version, which should give the browser another speed boost.

The upcoming Opera Mobile for Android will offer two notable features: hardware acceleration and pinch-to-zoom. The former is a technology which speeds up software performance, by offloading some of the processing from the CPU to other hardware components, usually the GPU. The latest version of Internet Explorer, IE9, for example, uses hardware acceleration to speed up text and video rendering and the performance of web applications.

In Opera, the technology is enabling the second of its two main Android browser features, pinch-to-zoom. In Opera's two other mobile browsers, Opera Mobile and Opera Mini, there are only two levels of zoom - on for the full page width and one zoomed in for reading text.

With pinch-to-zoom, however, Opera Mobile for Android users will be able to choose their own zoom level just as in the Opera desktop browser. Using the now-standard "pinching" gesture on the phone's touchscreen, zooming will be a more fluid experience, says Opera on its company blog today.

This hardware-accelerated zooming will also later arrive to other Opera browsers, including the iPhone version of Opera and its newest desktop browser, Opera 11.

Opera Mobile for Android will be available from both m.opera.com and Android Market within a month.

Opera 11

No exact launch date was available for Opera 11 - the company just says that the alpha version will be available "soon" from here: opera.com/browser/next.

The biggest news regarding this update is the support for extensions, a long-requested feature among Opera's core legion of fans. Like competitors Chrome, Firefox and Safari, the new extensions will be built using standard Web technologies like HTML5, CSS and JavaScript. This will make it easy for developers to port their extensions from other browsers to Opera.

In the first release, the extensions API (application programming interface) will support injectable JavaScript, callouts, certain UI items and a basic Tabs and Windows API.

At a press conference in Oslo, Norway, Opera demonstrated a couple of the first extensions - one for searching Wikipedia and another for use with user-generated news site Reddit.

• Wave Sudoku (play Sodoku with friends in a Wave)
• Extension Installer (for developers only)
• Colcrop (game)
• Yellow highlighter (highlight text)
• Napkin gadget (for doodles)
• Waffle (date-picker)
• Iframe gadget (embed webpages in a Wave)
• Yes/No/Maybe gadget (for polls)
• Map gadget (insert maps)
• Video Chat Experience (chat in Waves)
• Phone Conference (call your friends)
• Mind Map gadget (collaborate on diagrams)
• Likey gadget (like/dislike a topic)
• Pollo gadget (for surveys)
• Take-out gadget (for ordering out)
• AccuWeather (weather forecasts)

Will Extensions Bring You Back to Wave?

With Google Wave soon becoming a member of the Google Apps family of products sometime this year, it's good to see development work continue on this innovative, if somewhat confusing, real-time tool. Although members of the tech community have expressed mixed feelings about the product in its current state, what Google has presented is definitely a unique service and one that may still be useful in several niche scenarios, if not as the email replacement some hoped it would be. For example, small teams in the workplace needing to collaborate with one another may find Wave a better option than sending multiple emails back and forth.

That being said, traffic to Google Wave has been declining sharply since November or December of 2009, depending which analytics service you use. Looking at the numbers, it's clear that Wave has been abandoned by many of its earliest adopters - users who were once clamoring for invites in ways that haven't been seen since Google first launched Gmail. (On that note, we actually have several spare invites sitting around - if you want one, comment and ask.)

Will extensions actually bring those one-time Wavers back? Probably not - at least, not for longer than a quick look at most. On the flip side, however, Wave advocates feel that there's great potential in this experimental project. Still, even most of those folks have to admit there's a lot of work that needs to be done before Wave could attract a mainstream audience.

So will Wave ever replace email? Perhaps not. But we wouldn't be surprised if some of the innovations developed in the Wave playground ended up in our Gmail inboxes one day. And for that, we'll keep one eye on Wave...even if we're not entirely embracing it just yet.

Put out by the Computer Science and Artificial Intelligence Laboratory at MIT, the browser extention is a "tool to help people cope with information overload and to stay organized" that has since helped me keep track of the common threads of an often multi-threaded day.

Big Features for a Little App

There are just four hotkeys to remember: One opens and closes the frame, one searches through your notes, one pops up a quick entry bar at the bottom of your browser and one adds the current URL.

The list items are kept in little boxes, which can be rearranged simply by clicking and dragging. A click on the main area of a note opens it for editing and directly clicking on a URL will open that website in a new tab. A click on the "x" deletes the item.

Information for a Twitter Generation

This might be one of our favorite parts of this little app. While we can use the browser's bookmarks or services like del.icio.us, we don't have to spend time keeping our list organized in the same way. There's no complicated and powerful bookmark organizer. List.it is for parceling off your information into little bites, manipulating them and working with them along the way. As long as you tag your notes along the way, these saved searches act as filters. If that hashtag appears anywhere in the note's text, it will be displayed when you click on that search button, which is kept just below the search bar.

List.it also allows for synchronization between different browsers by saving your list on a central server, that way you can take your list with you on your netbook or your iPhone. One caveat - we ran into some difficulty while trying to create a user name and password. After installing list.it, there will be an orange triangle next to the text entry box at the top. Clicking on that will bring you to the proper location. Aside from that, we've had no other problems, which is always nice to see with an open-source, always in development type of app.

We'd recommend going and taking a look at the extension for yourself. It's available for Firefox version 3.0 or greater and for iPhone and Android. The video included below gives a quick preview off the extension, but we think using it will really prove its usefulness.

Greasemonkey, previously only a Firefox add-on, lets you customize the way a website is displayed using small bits of Javascript, and we're excited to see it added to one of the faster, tidier browsers available.

Greasemonkey scripts perform a variety of nifty little functions, from autofilling Twitter usernames to hiding links on Digg that you've already dugg.

While users were able to manually install Greasemonkey scripts before Chrome 4, this latest version provides native support and one-click installation. We gave it a quick test run and everything was just as advertised. Pick a Greasemonkey script, read up on it, and if you decide you like it and trust it, click install. Voila!

We'd been expecting this development since December, when we noticed that Boodman had been hired onto the Chrome Extensions team. It looks like the day has finally come. If you'll excuse us, we have a couple thousand new browser tweaks we need to go check out.

Google first made extensions for Chrome available in a developer release in December. Since then, developers have created over 1,500 extensions for Chrome. Some of the most popular include an extension that checks your GMail for new messages, an extension that allows users to open certain sites in an Internet Explorer window inside Chrome, as well as various ad blockers. Google also just updated its own Google Voice extension for Chrome.

Here at ReadWriteWeb, some of our personal favorites include Type-ahead find and the Google Similar Pages extension.

For now, the only stable version of Chrome that supports bookmarks and extensions is the Windows version. If you want to use extensions on the Mac, you will have to switch to the developer preview channel. For Linux users, extensions are already enabled in the beta channel.

Bookmark Sync

Starting today, the stable version of Chrome will also feature Google's bookmark sync. We reported that Google was planning this feature last August and the first version to support bookmark syncing was released in early November. Right now, this feature only supports the syncing of bookmarks, but as our own Sarah Perez pointed out last year, the infrastructure is flexible enough to also allow Google to sync other data (passwords, favorite sites on the New Tab page or your browser history) in real time.

With Weave, Mozilla is working on a similar project. For the time being, however, this is just an extension and not a core feature of Firefox.

Developers can contribute to the project by uploading creations to the Developer Dashboard here. If you need ideas, a good place to start would be to look at the "Most Shared" in the Firefox Add-ons Gallery and think about how you can port some of those gems over for the Chrome experience.

We got to try the Ribbit and 6rounds extensions first-hand over the last few days and they have turned out to be pretty interesting.

The Ribbit conference call extension allows you to quickly set up a teleconference in Wave. Calls can be routed to any phone, and you can use the wave simply to provide context for the call or to keep notes. Because Google doesn't currently give developers direct access to contact information, you have to type in your own number, but otherwise the operation couldn't be any easier.

While Ribbit focuses on telephone, the team at 6rounds has built a video chat gadget. Currently, 6rounds supports only one-on-one chats, but even given this limitation, the app builds nicely on Google Wave's real-time emphasis and allows you to watch YouTube videos or play games with your friends.

We didn't get to test the Lonely Planet, AccuWeather and LabPixies extensions yet, but they all look pretty useful as well. When we talked to the Wave team earlier this week, they especially raved about LabPixies Sudoku game, which looks to be quite addictive.

A Few More Things to Do When You Get Your Wave Invite

• Invite your friends. You will be able to nominate up to 8 of your friends for a Wave account. Wave is a lot more fun when you have somebody to help you test it.
• When you start a new wave, click on the Google icon. From there, you can add links and search and embed YouTube videos and images.
• Try to add a map (just click the Google Maps pin). As you scroll, everybody else in the wave will see a live update of what you are doing.
• Need to vote on where to go for dinner tonight? Try the Yes/No/Maybe gadget.
• Try the 'playback' feature - it replays a wave step by step. This comes in really handy if you want to check who has made what revisions.
• Invite a robot to your wave. Just add elizarobot@appspot.comto your contacts, for example, and you will have a robot shrink to chat with while you're waiting for your friends to sign up.

And a Few More Things to Remember

• Wave works in most modern browsers (and even runs on Safari on the iPhone), but it works best in Google Chrome (IE users will be prompted to install Chrome Frame).
• To add a contact to a wave, just start a new wave and drag and drop the icon from the Contacts sidebar to the new wave.
• The blue lines that appear when you scroll through a list show you where your reply goes. Just click on the line and a reply will show up.
• Pressing 'Enter' will take you to the next line in your reply - you have to hit "Shift + Enter" to finalize your reply.
• Private replies are hidden in the pull-down menu at the right edge of the message that you are editing.
• Stuff will break - remember that this is a very early beta!

Feel free to post a comment if you have additional tips and tricks (or favorite robots and extensions) you would like to share.

In addition, Google has also added some new features for extension developers, including the ability to "load an extension and pack an extension" more conveniently.

A small ecosystem of Chrome extensions is already growing up around Chrome, even though only a small number of Chrome users are currently able to use them. Once Google enables these extensions for all users, they will be able to use a wide range of them. The absence of extensions has held back a lot of users who may want to use Chrome but rely on certain extensions. Now, however, it looks like it's only a matter of time before all Google Chrome users will be able to tap into this growing extension ecosystem.

Given how stable both the beta and developer channel versions of Chrome on Windows are at this point, we hope that Google will soon upgrade the stable version to the 3.x or 4.x series, as they offer a lot more functionality. The Mac and Linux versions are currently still somewhat unstable, but at least the Mac version has now become quite usable.

Zotero also announced a new online component to its plugin, which, in conjunction with the new synchronization features, automatically creates an online backup of your database on Zotero.org.

Zotero, which we highlighted as one of the top application for students last year, features an extensive set of tools for creating and managing bibliographies. While it started out as a very basic tool, its feature set is now up to par with that of other commercial bibliography tools like EndNote or RefWorks.

Zotero integrates tightly with Firefox 3 and allows you to quickly save articles and easily create bibliographies for your papers and articles from most of the major free and for-pay research databases and online newspapers.

The synchronization feature works exactly as advertised and allows you to keep your bibliographies in sync, even if you work on different machines. If you have access to a WebDAV enabled server, Zotero can also sync your attachments automatically.

Needs Firefox 3

Whenever Zotero recognizes that you are surfing a supported site like Google Books, Amazon, YouTube, the New York Times, or JSTOR, it will simply add an icon to your Firefox address bar that allows you to save the bibliographic entry for that page or article with one click. Zotero will automatically extract the bibliographical information for you and it can even create a full-text archive of your saved documents.

Social Networking

Zotero.org now also includes a number of social networking features. You can, for example, search for other users by name, email, affiliation, or discipline. While this feature is still very new, and hence only has a few users so far, this could turn out to be a real boon for academic researchers (and others) who could use this to share their bibliographic databases with colleagues. In the future, Zotero plans to extend this with a Twitter-like stream of your friends' research activity.

Zotero also integrates with Microsoft Office and OpenOffice (though the 1.5b1 version is not compatible with these plugins yet!), and supports over 1,100 different styles, as well as the ability to create your own. You can also just drag and drop entries from Firefox to any other document and it will create a bibliographic entry for you on the fly.

Verdict

Zotero was already one of the best tools for managing large bibliographies. These updates make it even better and allow it to compete directly with its commercial brethren. The new synchronization feature allows you to work on different machines, without having to constantly save and update your database, something that used to give RefWorks (which is essentially an online tool) the upper hand.

Note: While the new sync feature worked great for us, Zotero rightly recommends that you back up your database before you update to version 1.5b1.

According to Mozilla's Justin Scott, 861 add-ons make up 95% of the total usage, while the other 5% are distributed among close to 5000 add-ons. 94% of the top add-ons are currently compatible with Firefox 3.0.

According to Mozilla's compatibility dashboard, as of today, only about 28% of the top 861 extensions are compatible with the latest builds of Firefox 3.1.

Getting to 95%

Currently, Mozilla's evangelism team is trying to reach out to all Firefox developers to make sure that everybody is ready by the time Firefox 3.1 is released. The release date for Firefox 3.1 is currently a moving target, but the second beta version should be available to the public by the end of this month, which might be followed by a third beta before the final version is released.

Some extensions, of course, are abandoned by their developers over time, so it might not be possible for Mozilla to get to the 95% mark for Firefox 3.1, but given the importance of Firefox and the extension ecosystem around it, it is good to see them reach out to developers proactively. For developers, getting ready for 3.1 should also be a priority, as Firefox users tend to update their browser very quickly after a new version is released.

For more information about the transition to Firefox 3.1 for extension developers, have a look at Mozilla's 'Add-on Compatability Center,' which will soon also feature additional tools for developers.

VideoSurf, which by itself is a very good video search engine, uses its proprietary algorithms to identify the most interesting moments in these videos and allows you to jump right to them by clicking on the images in the film strip.

The only problem with this script is that it won't take you to directly to YouTube or MetaCafe to see the video, but to VideoSurf itself. This makes sense, given that the script is a way to promote VideoSurf's search engine, but it would be nice if you could have a choice of destinations.

Overall, this is one of the coolest and more useful Greasemonkey scripts we have seen lately and definitely worth a try.

Here is how to install the script:

1. Install the Greasemonkey extension for FireFox (if you don't have it installed already) and restart your browser.
2. Click on this link to the script and then follow the instructions on screen.
3. You're done. Start searching!

Installing The Fennec Extension

Shortly after Finke created the mobile-ready version of URL Fixer, the addons.mozilla.org web site was updated to include support for the Fennec browser. When Fennec users visit the site, it will recognize that they're coming from the mobile browser and will offer direct installation via an "Add to Fennec" button.

After a required browser restart, users will see the new extension available from the Fennec Add-ons Manager, where it's also possible to access preferences and disable or enable add-ons.

Mobile Add-Ons Are Fennec's Killer Feature

The idea of being able to use add-ons in a mobile browser is definitely going to be a huge selling point for the Fennec browser when it goes to launch as it will be the first to support third-party extensions. It opens up a world of possibilities that take advantage of the new platform, too. Is it possible we'll see add-ons that allow you to interact with your phone's functions itself like "click-to-all" or "copy to my contacts"? That may depend on the mobile phone itself and how locked down it is. Still, we imagine that developers will soon be thinking of all sorts of unique add-ons that work best in a mobilized environment.

What sort of add-ons would you want to see in a mobile browser? Let us know in the comments.

Semantinet provided us with 400 invites for our readers. You can find more details about how to claim yours at the end of this post.

Depending on Silverlight might seem like a risky move at first, but a fresh install of Silverlight takes less than 10 seconds and Semantinet argues that it decided to use Siverlight instead of Flash because of its better privacy controls and in order to achieve its design goals.

How Does it Work?

Headup's mission is to connect you with your friends' activities across different social networks and to learn about your likes and dislikes so that it can make recommendations for you. Headup will add little icons to items it recognizes, which can be names, songs, videos, etc.

You activate headup by clicking on these icons. If a friend likes a particular song on Last.fm, for example, it will give you the option to play the song in the headup window, see when the band will play in your town, and what your friends thought about the song. If headup recognizes a person, the pop-up will also give you information about their latest Twitter updates, or Last.fm plays.

After the install, headup already works without having you having to set anything up, but once you import your contacts, it will go out and look at your personal connections from Twitter, FriendFeed, or Gmail.

Headup can also make use of Yahoo's Fire Eagle geolocation service to provide you with relevant local information. Headup will also make a limited set of recommendations, though this is not the focus of the product. After it recognizes your tastes, for example, it can recommend YouTube videos you might like.

Headup smartly stays out of the way when you don't want to use it. Overall, headup is a very useful little tool and it will only get more powerful as Semantinet connect it to more services.

Invites

If you want to try headup yourself, head over to the beta sign-up page and use 'RWWCODE' as your invite code. Once you tried it out, feel free to let us know your thoughts about it in the comments.

SemantiNet Introducing: headup from SemantiNet Ltd on Vimeo

According to Evan's email:

Extensions.flock.com has had a bumpy history. There's a fundamental issue here: there are very few Flock-specific extensions, and a great many Firefox extensions that are already hosted on addons.mozilla.org. The architecture behind extensions.flock.com is not mature, and we have historically been unable to devote valuable developer resources to this.  It's unrealistic (and doesn't make a lot of sense) to try to create our own system on the level of addons.mozilla.org until we have more Flock-specific extensions. Our admiration for the work Mozilla has done extends to addons.mozilla.org...AMO really is the best experience for getting extensions. With that in mind, we have cut the fat that is our unwieldy extensions system.

Sorry Developers, We Took Down Your Flock Extensions

The email goes on to inform the developers that the company had removed all the extensions from the site that are not Flock-specific - that is, any extensions that take advantage of some unique feature within the Flock browser itself. In addition, the Drupal back-end from extensions.flock.com has been removed which means no more comments or ratings on posts and no more automatic submission system. Any developer wanting to submit an extension going forward will need to email extension-submission@flock.com instead.

For visitors to the Flock web site, the new extensions page will point them directly to addons.mozilla.org.

According to Flock, the changes will allow the company to move forward focusing only on Flock-specific extensions, and finally, themes. As we noted earlier, customization is an important aspect to the browser experience. Something as simple as being able to skin Flock could make the transition easier for those making the switch.

Flock's Real Message: We're Just A Version Of Firefox

We think Flock's decision to separate their extensions from Firefox's extensions is a good one. Although their email promoted the idea that this just freed up time for Flock to focus on other aspects of their project, that's probably not the whole story here.

Flock wants to appeal to the social media crowd, a group that typically includes a large number of Firefox users. But in the past, Flock had set themselves too far apart from the Firefox community and gave off the impression they were really an alternative browser. Now that Flock has upgraded to the Firefox 3 codebase and lets you use nearly all the Firefox extensions, the message they're sending is that they aren't that different after all, they're just a version of Firefox 3 with nifty social features. In other words, you get the best of both worlds: Firefox 3 and social media integration.

Will this change in direction work and help Flock pick up some steam? It's possible. If you can move to a new browser which works like your old one and take all your extensions with you, the experience is much less painful. Now all they need is some sort of extension import wizard and we'll be all set.
