For a few months now Firefox will not start after I reboot my computer. In order to get it to start I click the exe then must go into task manager kill it, click the exe again, kill it again then, from there it will typically start, but sometimes it may take one or two more trys. When clicking the exe firefox will appear in the task manager under processes but will will start with ~7% CPU usage, then quickly drop to zero every time until it does actually open and start. I have ran a full system recovery and started anew after reinstalling mozilla several times failed to fix the problem. I run virus and spyware checks often and come up clean, and also run Chrome as a default browser.

This happened

A few times a week

== Around the time 3.5 was released

Hello Tom.

You may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in safe mode and select Disable all add-ons. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See this article for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.

If you want support for one of your add-ons, you'll need to contact its author.

I have tried this before, and run all the same plugins on another computer.
