Firefox does not show in Task Manager
OK, troubleshooting info on button below did not work. I can't get Firefox to open ever since it updated. I tried to restart my computer, uninstall Firefox, nothing is working. I thought maybe Firefox was running in background, but when I checked Task Manager to see if I could End Task, there was no sign of Firefox. I want to reset Firefox, but can't figure out how without access to browser.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
If the above does not work, do it again, but click on Refresh.
Your original user profile will be saved to a folder on the desktop with some data copied to the new profile history, bookmarks, passwords . . . . .
Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;
- Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
- Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see
