Firefox has been working fine here for many years.
windows 10 x 64
Last week, suddenly both Thunderbird and Firefox stopped working. (I'll open a Thunderbird thread too, as it's slightly different)
In Windows safe mode - Firefox works fine.
In normal Windows - it used to load once, and then not a second time (I'll get to that), now it doesn't load at all.
The thing is - it starts a process but cannot kill it. So when it used to start, it wouldn't reload, because (I think) it thinks it's already running. it gives the message that the old process must be closed.
I can't kill these processes - it says "access denied".
Now it doesn't really start at all - even in (Firefox) safe mode.
It starts a process though - so it's starting to load, but it's not getting far enough.
If I try again, though, it will give the message that it's already running.
I've tried all the re-installs etc etc - but it's too much of a coincidence that both Firefox and Thunderbird broke at the same time.
It must be a Windows issue.
Nothing much has changed, and the only Windows updates recently were .NET ones - which shouldn't really affect this.
The other weird thing is - I've restored images from a few weeks ago (when everything was fine) and I still get the same problem.
Has anyone seen anything like this before? Or am I on my own
I've tried all the fixes I could fine (parent.lock etc) but it basically comes down to this:
1 - both Thunderbird and Firefox, if they can be persuaded to load once, will never load again (until a reboot) because they can't kill the process from the previous load.
2 - it happened to both Thunderbird and Firefox at the exact same time.
Thanks for any ideas.
