If you are a fan of Firefox, you may want to get this one.

The first RC (Release Candidate) of Firefox web browser is now available for download at ftp.mozilla.org. If you have trouble accessing the above link, use this direct link to download the Firefox 4 RC1 installer for Windows. The Mac version of Firefox 4 RC1 is here while the Linux version is here.

This Mozilla page has a list of all news features that are part of Firefox 4 beta, including the compact start button, and am not sure if much has changed in the latest RC.

Interestingly, the final release of Internet Explorer 9 is just round the corner.
