Recently upgraded from Firefox 3.6.13 to Firefox 13 - freezes when trying to open
I've been using firefox 3.6.13 for some time now; the reason I have such an older version is because it's for a work computer, and an upgrade to newer versions generally isn't seamless and can interrupt the process of work.
Any way, I find some down time and decided that I'd upgrade to the latest version of firefox. Every thing seemed to install fine, and it copied over all of my addons apparently (which I'm grateful for). How ever, when opening up Firefox it opens and displays two tabs saying "connecting", but nothing happens beyond that. It just freezes completely providing the "waiting" icon when hovering over it. I tried waiting 10+ minutes for what ever process was holding up to complete, but nothing happened. In order to close out of firefox I need to kill the process in task manager.
I've tried uninstalling and reinstalling, but the same issue occurs. I tried looking for previous, more stable, versions of firefox but couldn't find any thing.

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.
See:
Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If the new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Problems with Flash content can be caused by a recent Flash 11.3 update.
