Firefox crashes at every start even in safe mode
New computer with Windows 10 64 bit, Firefox crashes every time I start it even in safe mode, causing computer to shut down and creating blue screen with memory management error. Latest version of Firefox, installed about 3 days ago. Tried to install dotnetfx for a programme I downloaded - unsuccesfully. Aborted automatically - causing blue screen as above.
I get the following error message: C:/Program Files (x86) Firefox mozglue.dll is either not designed to run on windows or it contains an error. Error Status 0xc000012f
I tried "%APPDATA%\Mozilla\Firefox\Crash Reports\submitted" - comes up with folder not found... Firefox Version 4.42.0.0 Windows 10 Home 1709

Try uninstalling Firefox and reinstalling it
Do a clean reinstall of the current Firefox release and delete the Firefox program folder before installing a fresh copy of the current Firefox release.
- download the Firefox installer and save the file to the desktop

If possible uninstall your current Firefox version to cleanup the Windows Registry and settings in security software.
- do NOT remove "personal data" When you uninstall the current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
- (64-bit Firefox) "C:\Program Files\Mozilla Firefox\"
- (32-bit Firefox) "C:\Program Files (x86)\Mozilla Firefox\"
- it is important to delete the Firefox program folder to remove all the files and make sure there are no problems with files that were leftover after uninstalling

Your personal data like bookmarks is stored in the Firefox profile folder, so you won't lose personal data When you uninstall and reinstall or update Firefox, but make sure NOT to remove personal data When you uninstall Firefox as that will remove all Firefox profile folders and you lose your personal data.
Thanks! I'll try that as soon as I have a spare moment. I'll keep you posted...
