''I accidentally hit the clear recent history & clear download list'' I think that button may be a bit more protected from accidental discharge in Firefox 6 than in Firefox 4 and ask you a question about how much you want to delete.

You asked about how to create a backup, so that implies that you do not have backups of your applications. If you had a backup of your profile you could restore places.sqlite back to your profile with Firefox down. First thing would be to make your browsing history safer -- check your settings for '''Tools > options > Privacy'''', make sure you are not clearing more than just cache in "Settings for Clearing History" * http://img232.imageshack.us/img232/4928/clearcachew.png * clearing your history at end of session, cache is the only one you would want to clear at end of session, if you don't want to lose things.

Of course it would be better to backup all your profiles if you have more than one, and better yet to occasionally backup all of your application files.
