I can't open a second browser window.
If I have had a firefox window open and then closed it, I can't get Firefox to open again. I have to shutdown and reboot to be able to get Firefox to open.

That sounds like Firefox is "hanging at exit" and is usually caused by an Extension or a Plugin.

- In Task Manager, does firefox.exe show in the Processes tab?

- What may cause Firefox to hang at exit
- You may need to try Firefox Safe Mode
- You may need to use Safe Mode to locate the problem:
- See:
- Firefox 4 users, hold the Shift key while clicking the Firefox 4 desktop icon to enter Safe Mode.
- Firefox Safe Mode is a diagnostic mode that disables Extensions and some other features of Firefox.
- In Firefox 4, Safe Mode also disables Plugins and Hardware Acceleration.
- If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes before starting Safe Mode (In Firefox 4, Tools > Add-ons > Appearance). See: http://support.mozilla.com/en-US/kb/Using%20themes%20with%20Firefox#w_managing-themes-and-personas
- When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode".
- Test to see if the problem you are experiencing is corrected.
- If the problem does not occur in Safe-mode then disable all of your Extensions and Plug-ins and then try to find which is causing it
- by enabling one at a time until the problem reappears.
- You can also enable a few at a time (3-5), keeping track of what you just re-enabled to see if the problem re-occurs; this will help narrow down the possibilities if you have a large number of add-ons.
- You MUST close and restart Firefox after EACH change via File > Restart Firefox (on Mac: Firefox > Quit).
- You can use "Disable all add-ons" on the Safe Mode start window.

Thanks for the helping hand; the problem was one of the extensions loaded by Zone Alarm. I had not the slightest idea where to start looking until you took my hand.
