I recently installed Mozilla Firefox 4 beta but firefox 3 is still on my computer. How do i uninstall 3 without deleting my bookmarks, which seems to have carried over into 4 quite nicely, and other preferences?

See https://support.mozilla.com/kb/uninstalling+Firefox

Do not select the option to "Remove my Firefox personal data", if this option is selected it will delete all of your Firefox user data for all versions of Firefox. If the option is not selected, Firefox user data is left intact.
