Firefox crashing + corrupt downloads for the update

[Smithy]

In case your Firefox keeps crashing (after the damn beta version update) or you need some plugins to work again you can get an older version here - http://www.oldapps.com/ - since it doesn't allow a rollback. If you uninstall and reinstall an older version it should save your bookmarks.If you uninstall the Mozilla maintenance service it won't keep pestering you to update. They have an awesome archive of with older versions of apps.

If you're planning to download large files or if you're having trouble with corrupt downloads of the new update or just in general try Free Download Manager - http://f0.freedownloadmanager.org/fdminst.exe . Handy little app but the guys were nice enough to give us a torrent as well so you can use that too.
