Chris said that current stats indicate that Firefox usage peaks mid-week, as opposed to the weekends - which he said is the reverse of what it was two years ago when they launched Firefox. He thinks this does suggest strong usage within the workplace. He also said they're hearing that more and more IT departments "are moving over" - certainly in some of the larger tech-oriented firms, like IBM, where Firefox is being used internally.

User Experience and Security

Talking about the Firefox upgrade, Chris said that the two key things they focused on in FF2 were 1) tuning the user experience - making it more efficient and enhancing customization; and 2) security. 

In terms of the user experience, Chris mentioned the tweaks to the tabs, undo close tab, "session restore" and search suggestions as examples of improvements to usability. He also said that Firefox 2 focuses on bringing capabilities that are typically found in desktop apps, into the browser - inline spelling is the most obvious such feature. They support multiple languages too.

For security, Chris said they're very proud that Firefox has the fastest response time of any vendor - they respond to security issues in days, "as opposed to the weeks and months that you might see from other vendors". He also said Firefox looks to be very proactive in security - e.g. their Phishing Protection. Using plain, everyday language is also a feature in FF - so they don't use the term "phishing" for example in their pop-up messages.

Web Feeds

In Firefox 2 they have extended the lightweight feeds integration approach of Live Bookmarks, by making it easier for people to recognize and make use of feeds (providing summaries, options for RSS Readers). 

I asked Chris whether they have any plans to integrate their own (fully functional) RSS Reader into Firefox. He replied:

"We've evaluated between: should we make Firefox a fully featured news reader, or should we make Firefox awesome at content discovery and handoff? We decided that the browser should be about helping you find information and then channeling that information to an appropriate service. [...] at the same time there are add-ons or extensions which do integrate and add fully featured news reader services to Firefox [...] such as Sage."

I asked whether Mozilla might, in the near future, re-visit that decision to not integrate an RSS Reader (by default) in the browser? Chris replied:

"We see that RSS is still very early in its adoption and use overall. The people who seem to be currently using it to great effect are newshounds [...] We're already, in terms of future product planning, thinking about how is RSS really just a basic capability - like HTML is - and what is the real use case and what is the real adoption. I think things like MyYahoo and iGoogle, in terms of personalized news where you don't need to know it's RSS, is along the lines of where things will be heading. And certainly we'll evolve the browser as appropriate. But at this point we've erred on the side of giving people maximum flexibility to manage RSS in any way in which they choose."

Personalize your browser

Extensions (now being called add-ons in the 2.0 timeframe) are a key feature of FF2. It keeps the core browser streamlined, while allowing users to personalize their browser with add-ons. 

Chris said that the add-on space "has really mushroomed in the last year". They now have close to 2000 add-ons for Firefox, from shopping comparison add-ons to blogging add-ons and a lot in between. He says there's "huge amounts of innovation" in the add-on space - and they're using it as a kind of test bed, pulling ideas from the add-on space into the core product as they move forward. He says add-ons are easy to build too and are similar to creating web apps.

Offline Browsing

Chris mentioned that their implementation of the WhatWG DOMStorage specification may potentially enable offline browsing. Right now they don't know of anyone supporting these offline modes for their applications yet, but going forward Chris sees offline browsing (e.g. composing email on the plane) as a significant step forward. So Mozilla is helping to implement the building blocks of that offline browsing concept.

Why 2.0?

I asked Chris the reason why the upgrade is a 2.0 release, rather than a 1.x:

"It's more sort of a natural evolution. It felt to us like a 2.0 product, particularly if we looked at it from what 1.0 was, to 2.0. It was like half steps, from 1.0 to 1.5 to 2.0. It's also a very stable and rock solid release - it's really ready for the masses. So it really does feel like a 2, as opposed to a 1.x product. Firefox 2 has, we estimate, between 3-4 times the number of fixes than FF 1.5 did. And that doesn't just include fixes and bugs, but all of the feature work as well as memory, stability and security issues. But there's certainly a lot in it which makes it really solid."

The Future of Firefox

Finally, I asked Chris for his thoughts on the future of the browser. He said:

"[...] if at some level the browser can move into the background, and it's really the web content that's the most important thing and the ability for you to cleanly interact with your online life [...] it really shouldn't matter whether you're accessing your content from your computer, your phone or your tv - we're going to see consistency in that experience."

In closing, Chris told me that Mozilla is "really excited about the fact that the Web is again evolving - and there's a tremendous amount of innovation going on in terms of browsers as well as web 2.0". He said that Mozilla and Firefox have demonstrated that "the browser does matter", that it has enabled and empowered better experiences and will continue to do so.

Chris concluded by saying that Mozilla will constantly look to push the envelope and we'll see a lot more from them yet - and from the Web at large too.
