The release is a security and stability update. A total of nine security vulnerabilities have been fixed in the update including four critical vulnerabilities. You can access the list of security fixes at the Security Advisories page for Firefox 3. The release notes do not contain information about the stability updates but the full list of bug fixes mentions a few fixes that stop browser crashes.

Lastly language support and language related additions seem to have been a priority. Firefox 3.04 adds support for Thai and Icelandic as well as beta test releases for Bulgarian, Esperanto, Estonian, Latvian, Occitan, and Welsh.

There have also been several important bug fixes for the following annoying problems:

• Fixed an issue where some passwords saved using Firefox 3.0.2 did not work properly.
• In some cases, Firefox would not properly save proxy settings for protocols other than HTTP
• Fixed an issue where the IME input tool used to enter Japanese, Korean, Chinese and Indic characters was covered by the “Add Bookmark” panel

Firefox 3 users are asked to update as soon as possible. All updates that had been installed on a test system were not affected by the update and it is unlikely that many will be. Let us know if you encounter problems after installing or updating to the new Firefox release.
