What to do when Firefox Browser does not Start Up
The best feature of Firefox is the support for 1000s of Add-ons to increase the features. Sometimes Firefox fails to start up because of some add-ons. When Firefox is opened, it runs in background and it is present under the processes list in task manager but is not listed under applications that are running. This is a common problem with Firefox and the solution is also simple.
1. First go to Task Manager and end process “firefox.exe”.
2. Go to programs -> Mozilla Firefox -> Firefox (safe mode)

3. In the check list select for defaults and disable all add-ons.
4. Click make the changes and restart.
Now Firefox will start normally without any issues.
Share & Enjoy

Good tip (though making a new profile with the firefox.exe -P command on run is also possible, as new profiles don’t have extensions).
I never use more than 5-6 extensions, because more will only make an otherwise decently fast browser pathetic and slow.

@Sumesh,
Thats also a good way, to create a new profile.
Even if you use only 5-6 add-ons, an update in a single add-on can cause firefox to stop starting up.

I have the same problem. Even Safe Mode does not open. I had some viruses. I believe that is when it started. I have removed the viruses but still no Firefox. I have uninstalled it and re-installed (fresh download) but no luck.
HELP. I will not use IE. Also (may be related), if I search with IE, Yahoo, when I click on a serach result, it takes me somewhere else. Not where I clicked.
