The first release candidate of Firefox 3 is now available for download in 45 languages, not long after it was reported that the RC1 code had been completed. This part of the process is mainly aimed at getting user feedback before the browser enters the final release stage. Firefox 3 contains a number improvements over FF2, many of which we have reported on previously. If you want to get the low down on exactly what's new, then you should read the full release notes here. If you do decide to install RC1, you should note that add-on support is likely to be lacking and that unlike previous beta versions, it will overwrite your FF2 installation.
