Firefox keeps quitting after launching in a computer lab. It's very strange. Is there a log? about:crashes gives nothing. This is windows 10 1709. It doesn't matter what Firefox version, 32 or 64 bit. I can't find anything in process monitor.

I figured it out. When I uninstall Netop Vision client 9.3 https://www.netop.com/edu.htm, Firefox works fine. I don't know how Firefox could possibly conflict with a screen sharing software. (As well as Cisco Amp antivirus, but that's now resolved.)

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

It seems to be running ok now by itself now. I suspect something changed on the firefox servers. I did manage to send in two crash reports.

The version didn't matter. Vision 9.5 works with Firefox ok.
