firefox, why you tryin to hurt my heart?

[fox]

So some time last night, Firefox started freaking out on me.  The automatic Google-search in the search bar to the right of the location bar? disabled itself.  I had to install a whole specific Google toolbar.  Then when I try to customize my toolbars (and put the Google bar up where the search bar used to be), it works, but never stays that way when I close Firefox and reopen it again.  Frustrating, but I can live with it.

Now today it's stopped allowing me to set bookmarks.  I click 'bookmark this page' and I get the popup box asking me what folder to put the bookmark in, but when I click 'OK', the box doesn't go away and the bookmark doesn't set.  I thought maybe I had too many bookmarks, so I deleted one and tried to add one back -- didn't work.  I uninstalled and reinstalled Firefox -- same story.

Help!
