I tried to download Internet Explorer for Mac and Firefox crashed. I downloaded another Firefox and it asked me to update some programs and it crashed again. I have Firefox 2.0 as i managed to open that but would really prefer my most recent one. I have never had this problem before and have been using Firefox for years now. I can use Safari and Google Chrome but want Firefox as it has all of my bookmarks and saved things. Help!!! I sent a report but never heard back or got any crash ID.
