Firefox does not open after Windows 7 updates
After Windows 7 updates installed, Firefox 4.0.1 refuses to start. I click on the shortcut, the hourglass (blue circle in Windows 7) pops up for a couple of seconds, then it goes away, and no Firefox.
Chrome and IE work fine.
I have followed the tips on the "Firefox won't start" pages.
In Task Manager, there is a 4,796k Firefox process, which I then end. If I attempt to start Firefox multiple times, I get different processes in Task Manager, of different sizes.
I removed and re-installed Firefox 4.0.1. It made no difference. I even chose to have it delete all my customizations. No luck.
I cannot start Firefox in Safe Mode. When I try, the same thing happens (hourglass, then nothing)
I cannot start the Profile Manager. I created a new user in Windows, logged in as that user, and tried starting Firefox, but the same thing happened. This leads me to believe that it is not a profile issue.
I do not get a crash report.
Thank you for your help!

Which Windows 7 updates were installed? Were these rated as "Critical"?
Microsoft usually releases updates on 'Patch Tuesday' which always takes place on the second Tuesday of the month. That won't take place for another two weeks yet. I'm not aware of any out-of-band updates.
Thank you for the reply, Xircal.
I hadn't allowed Windows to update in weeks (couple of months?), and finally did this morning. The patches may or may not be new - See attached image for a partial list of what was installed.

Can you try creating a new Profile. See Profiles - Where Firefox stores your bookmarks, passwords and other user data.
If that fixes the problem, then you can move your data like passwords, bookmarks etc., from the current profile to the new one. See Managing Profiles
Did you check your security software (firewall)?

Thank you, Xircal and cor-el. I'm not sure what it was, but after I installed Windows 7 SP1, Firefox started working again! All is well. Thanks again.
