Firefox 53.02 suddenly became really slow.
Windows 10. FF suddenly became very slow, almost unresponsive. Starting in safe mode fixes this problem, but there aren't any extensions installed and I have refreshed FF and turned off hardware accel.

hi, we are currently aware of a bitdefender signature update that's cuasing some havoc for firefox users - are you using bitdefender security products on your system by chance? https://www.reddit.com/r/firefox/comments/69zsnj/help_super_laggy_firefox_browser_08052017/dhbles0/

Now FF also uses about 20% of the processor.

Yep, that's probably it. I use BitDefender. Why is it that I always magically choose the software combinations that cause havoc?
Bitdefender rolled back there free versions update yesterday and initial reports seem to confirm the issue is now resolved & bitdefender can be used as normal again.
