Although we doubt this will be the last release candidate, if you're a Firefox 3 user, release candidate 2 is now available to download. Whereas RC1 had a few minor visual improvements, so far we've yet to see anything obviously new in the latest version, apart from a few fixes and back-end updates. If you have Firefox 3 installed, you'll probably be more wise heading to the Help menu and selecting 'Check for Updates' as the browser will automatically download and install the correct version.
Alternatively, head to the Mozilla Firefox 3 RC2 download page and select the version you require for your system.
