since the update to FF 53.0 (and now also with 53.0.2) I've had it freeze on me 5 times and every time it also completely locked up my PC - mouse was frozen, Ctrl+Alt+Del didn't work, gave it 10 minutes but was still frozen afterwards - and I had to shut my PC down forcefully.
FF 53.0.2 (32 bit)
Win 7 (64 bit)
FF Addons: NoScript & AdBlock Plus
No changes in terms of add ons, no Windows updates or new programs that could have caused this. The only programs running in the background are/were my anti-virus/anti-malware programs, Skype, Outlook, Rainmeter and my mouse driver (all of which I've used for at least the last 6 months).
The first two times it happened when I tried to restore tabs from the "oops, that shouldn't have happened" page and the last 3 times when I opened a new tab (with 1-2 other tabs open at max, usually only an empty one!). The 3rd time was 2 weeks ago, the 4th time on May 9th when I opened a new tab after clicking on one of my tiles on the "new tab" page (no other tabs were open at the same time!).
Today it happened again! I installed a bunch of Windows updates a couple of days ago and this time I had Minecraft loading up and was watching a movie (DVD) in VLC (no Outlook running this time) but when I opened a second tab in FF, the picture froze again. The weird part is that the sound of the movie kept playing but it didn't let me move the mouse or open the Task Manager. I've never had a video run at the time of the freeze, so I don't know if Windows would have still kept playing the sound the other times.
I can play really hardware-intensive games that use 50+% of my cpu (not that there are a lot that do) and a lot of my gpu's power/VRAM and/or RAM (sometimes goes as high as overall 13gb/16gb) but I've never had any freezes just with games + watching a video at the same time, it always happens while opening a website through one of the tiles or a new tab directly in FF 53.x!
