I now can't start Firefox, i complains about it allready being running but not responding.
There's no Firefox processes in the task manager and I've tried rebooting.
Lucy is such a cunt.
Right -deleted the Mozilla folder again in apdata and I've got back into firefox, with flash working.
However, when I try and restore my bookmakrs and passwords and stuff from my old profile, it stops plugins working again.
Huzzah, I have now got it working with flash at least, and now about:addons works too!
I'm pretty sure the issues with 4.whatever it was were on a different laptop, at very least on a different install of windows. This install is pretty fresh, really.
And I seriously doubt malware is at fault, as this has only been online via 3G since I got it so i haven't downloaded anything really, just surfing and using Libre Office.
