A. Update: FireFox version 3.0 has been released and it is recommended that you install Firefox 3.0 under any Linux distribution.

Installing Firefox 2 will overwrite your existing installation of Firefox. You won't lose any of your bookmarks or browsing history, but some of your extensions and other add-ons might not work until updates for them are made available.
