I recently installed Mozilla Firefox 4 beta but firefox 3 is still on my computer. Can i safely uninstall 3 without deleting my bookmarks, which seem to have carried over into 4 quite nicely, or altering my other preferences?

Preferences are saved in Profiles - Where Firefox stores your bookmarks, passwords and other user data, so you can uninstall Firefox 3 without problem.

Be aware that Firefox 4 is still in Beta phase and the latest stable version of Firefox is 3.6.
