If the crash is NOT at startup you may need to read Troubleshoot Firefox crashes (closing or quitting unexpectedly)
- Uninstall Firefox from your computer.
- Delete the Firefox installation folder (located in one of these folders by default):
- C:\Program Files\Mozilla Firefox
- C:\Program Files (x86)\Mozilla Firefox
-
Download a fresh copy of Firefox.
- Double-click on the downloaded file and follow the prompts to continue the installation process.
