Firefox 8 is not officially slated to be released until November 8; however, the final builds for most platforms are already available on Mozilla’s ftp channels. Unlike the last few releases, Firefox 8 actually has a couple of new features that are worth looking into.
The biggest change is related to Firefox’s add-on installation and management procedure. On first launch, Firefox 8 presents users with a list of all the add-ons currently installed. Add-ons that were installed by third-party applications are disabled by default. If any third party application attempts to install a new extension, Firefox will seek the user’s permission before allowing the extension to be installed.
There is also a new option that forces Firefox to load tabs only when they are activated, while restoring windows and tabs from the previous session. This is a handy option that should reduce the start-up times for Firefox 8. However, it is disabled by default and needs to be enabled from Options –> General.
Other significant changes in Firefox 8 are: addition of Twitter to the search bar, improved tab animations, improved performance and memory handling when using HTML5
At the time of writing, Firefox 8 for Windows x64 was yet to be uploaded; however, you can find the new stable build for almost all other platforms here.
