I downloaded the last update, 24, which worked fine on local identities. When I try to open it in a server/network identity, it never opens, just hangs - I tried opening in safe mode (opt key + open, choose safe mode) and it acts like it will open, but never loads, and I can't click any buttons on the toolbar (or I can click one, but nothing ever loads). Resetting doesn't work either. It does the same thing on all computers, only server identities. I've tried creating a new profile, deleting old profiles, changing places suffixes to ".old", deleting prefs file - nothing worked. Firefox never opens, so I can't do any of the support related to the toolbar. I think it's related to an add-on, because it first crashed when trying to find compatibility with add-ons. It won't run in safe mode, though, so I can't tell. My next step is going to be trying to find where all the add-ons are located, and delete them manually, but I'm not sure where to start.

If anyone has any other advice, that would be great!
