Browser will not open after latest Windows 7 updates
I'm unable to open Firefox after recent Windows updates. Unfortunately I cannot resolve this through a system restore as I did a system clean up before I realised the problem and lost the restore points. I tried upgrading to Windows 10 as that should resolve the problem but have come up against the issue of the system automatically reinstalling the previous operating system (ie Windows 7) at the end of the download/installation process. I tried removing the firewall and virus protection but Windows 10 still wouldn't install after 3 attempts. Any suggestions on how to fix the problem of Firefox not launching, while staying with Windows 7, would be very much appreciated.

If I understand correctly, Firefox does not crash to the Mozilla Crash Reporter -- it just appears to go nowhere.
If you check your Windows Control Panel, Uninstall a Program, what is your current Firefox version?
A Recent Issue for 64-bit Windows Users with 64-bit Firefox
One of the main effects of the Firefox 56.0.1 update was to migrate 64-bit Windows users from the traditional 32-bit version of Firefox to the 64-bit version. We've received a number of puzzling reports of Firefox either not starting (probably due to incompatibilities with 64-bit drivers that Firefox expects/requires) or not loading any pages after this migration. One user discovered that Windows was silently killing Firefox at startup and recording it in the Windows event logs (you can view event logs using the Event Viewer). Based on one of the reports in the log, we were able to trace that to an out-of-date Logitech camera driver, of all things. Three other users reported that uninstalling the Logitech camera resolved their problem as well.

Do you want some assistance in looking at event logs, or do you have such a camera?
If the investigation doesn't yield any solutions, it is worth trying a return to 32-bit Firefox.
While normally this kind of change is seamless -- the installer detects your existing data and preserves everything -- you might want to make a backup "just in case."

I did indeed have an old Logitech webcam running which I've now deleted. It solved the problem and I'm now back into Firefox.
Thanks for your help, you just made my weekend!
