I've got FireFox 3 installed on my brand new iMac. For some reason when I make changes or edits to my bookmarks, they don't seem to save. So for instance, I could go into my bookmarks, and delete a few of them. I close the browser, open it back up and they're back. What gives? I don't seem to see any options after deleting them. I just close the bookmarks window, but that doesn't seem to be working for some reason.
