First off, Merry Christmas from the Guru! For those readers who were not around this time last year, I did an impromptu special feature called the Fx Year In Review. I thought it would be neat to look back and see what happened with Firefox that year, especially with the release of Firefox 2.0! I want to continue this as an annual Christmas tradition so here’s a look back at Firefox in 2007.
A lot of us were hoping to see Firefox 3 come out in 2007, however given the huge complexity of Firefox 3 (especially Places) this just did not happen. Now keep in mind for nearly the first half of 2007, there were three different branches of Firefox in development. There was the old 1.5.0.X branch which Mozilla phased out, 10 releases on the 2.0.0.X branch and then the very slow progression of Fx 3 with 9 releases (7 Alphas and 2 Betas).
- There were no Firefox releases during the month of January 2007.
Firefox 220.127.116.11 & 18.104.22.168 were both released together on February 23rd. Both releases fixed a Permissions
Bug in the German (de) locale on Linux.
Firefox 22.214.171.124 induced several security fixes
Firefox 126.96.36.199 fixed several issues for Windows Vista users:
- Automatic Updates now works with users who have limited account privilege and User Account Control
- Uses the Vista Default Application API which means Firefox should now be able to set itself as the default browser without having to be run as an administrator.
- Before Firefox would remain elevated (a.k.a. running as an administrator) after an update was performed, but that has been fixed.
- Fixed several security issues
Firefox 3.0a2/Gecko 1.9a2 were released on February 7th and came the following warning:
The browser may consume excessive amounts of memory after prolonged browsing. In order to better handle memory issues, a new garbage collection system has been implemented. However, as the process of integrating Gecko into this system is still ongoing, there are some known leaks that result in large memory usage when the browser is used for a long period of time. A restart should
resolve the problem, which will be fixed in Alpha 3.
Some of the improvements in this milestone included:
- Resolved remaining issues with ACID2 test compliance.
- Support for the Web Apps 1.0 API for changing stylesheets.
- XML documents can now be rendered as they’re downloaded instead of only after the full document has been loaded.
- Greatly improved Mac widgets support since Alpha 1.
- Improvements in the Cairo graphics layer.
Firefox 188.8.131.52 & 184.108.40.206 were both released together on March 20th.
Firefox 220.127.116.11 included several security fixes
Firefox 18.104.22.168 included these fixes:
- Various web compatibility regressions.
- Several security issues
Firefox 3.0a3/Gecko 1.9a3 were released on March 23rd. Some of the improvements in this milestone included:
- Animated PNG (APNG) images are now supported.
- The DOM clientLeft and clientTop attributes are now supported.
- Introduced support for <link rel="offline-resource">, which puts resources into the browser’s offline cache. This allows a web application to ensure that its resources are available in the cache when the browser goes into offline mode. See Marking Resources for Offline Use for further details on offline support.
- Improved precision of layout and scaling across a wide range of screen and printer resolutions.
- Implemented cycle collection in XPCOM, which detects cases where two released objects hold one another, but neither is held by anyone else. In this scenario, both objects can safely be purged. Previously, the holds each has on the other would have prevented them from being purged.
- Added support for the
HttpOnlycookie attribute, which marks a cookie as readable only by the server and not by client-side scripts.
- Added a new preference, “Warn me when web sites try to redirect or reload the page”, which notifies the user when the page specifies
Firefox 3.0a4/Gecko 1.9a4 were released on April 27th. Some of the improvements in this milestone included:
- New Page Info window
- Many Cocoa user interface improvements and bug fixes
- Improvements to offline application support. Enabled Listing of Offline Resources and implemented SQL device for the offline cache. See Marking Resources for Offline Use for further details on offline support.

This bug affected several web sites and extensions (FoxSaver, Fotofox) that rely on it to deliver the intended experience to their users. This was also the first time there were 3 releases on the same branch in the same month AND 2 in the same week.
Firefox 3.0a8/Gecko 1.9b1 were released on November 19th. Finally a beta release and it is official, Firefox 3 will not be released in 2007.

Many extensions, especially those pertaining to bookmarks, will probably not function to their full potential if at all.” Some of the improvements in this milestone included:
- Improved security features such as: better presentation of website identity and security, malware protection, stricter SSL error pages, anti-virus integration in the download manager, and version checking for insecure plugins.
- Improved ease of use through: better password management, easier add-on installation, new download manager with resumable downloading, full page zoom, animated tab strip, and better integration with Windows Vista and Mac OS X.

- Improved platform features such as: new graphics and font rendering architecture, major changes to the HTML rendering engine to provide better CSS, float-, and table layout support, native web page form controls, colour profile management, and offline application support.
- Performance improvements such as: better data reliability for user profiles, architectural improvements to speed up page rendering, over 300 memory leak fixes, and a new XPCOM cycle collector to reduce entire classes of leaks.
- All the changes/fixes/improvements are too numerous to list, see the Firefox 3 Beta 1 Release Notes for a complete list.

- Performance improvements such as: better data reliability for user profiles, architectural improvements to speed up page rendering, over 330 memory leak fixes, a new XPCOM cycle collector to reduce entire classes of leaks, and reductions in the memory footprint.
Closing Thoughts & 2008
All in all it has been quite a year for Firefox with the three branches. Hard to say if we will see this again next year with Firefox 2, Firefox 3…provided it ever gets released..and Firefox 4.
I know there is going to be a Firefox 3 Beta 3 and I don’t expect to see that until sometime in mid February 2008. I really think the developers should have waited on Beta 2 until after the holidays as it seems they were in a big hurry to push this out. Consider that it was almost 2 months between the Alpha 8 and Beta 1 releases and yet barley a month after Beta 1 they push out Beta 2.
How many more betas after this, I haven’t a clue. I sure wasn’t expecting to see 8 Alphas on Firefox 3, just hope we don’t end up seeing 8 (or more) Betas. Granted, Places has been a major reason for the multiple Alphas, but looks like they finally got the major kinks worked out.
Further haven’t a clue when the final version of Firefox 3 will be out. I hope it will be released by this time next year, though I wouldn’t be all that surprised if I am writing about Firefox 3 RC 8 (but I sure hope not) when I am doing the 2008 Firefox Year In Review.
2008 we could see another race between Microsoft and Mozilla to see who will release their ‘new & improved’ browser first. This was the case in 2006 with IE7 and Firefox 2. Now keep in mind there is little known about IE 8 other than it just recently was certified passing the Acid 2 test. As for a release date, that is about as unknown as that of Firefox 3
Should I even speculate on Firefox 4? Um…nope, not even go there.
