My fancy new Firefox 57 crashes a few seconds after starting. Every time. The crash reporter doesn't catch it, so you'll never know the details!! (Muahaha!!) Without a working browser window, I can't enter failsafe mode, nor reset Firefox.

Chosen solution

uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do : https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Reinstall with Current Release Firefox 57.0 with a Full Version Installer https://www.mozilla.org/firefox/all/

Update your Video Card Drivers.
