NOW WORSE - Application has been blocked from accessing graphics hardware (RAW DATA AVAILABLE)
RAW DATA IS NOW AVAILABLE BELOW.
THIS IS THE START OF THE ORIGINAL POST (the new stuff is way below):
The most recent version of Firefox for Windows 10 repeatedly crashes. So far it has not occurred with other browsers. It occurs when I scroll and reach a point on a web page that contains an embedded video. As it does not always happen, I assume there must be a separate trigger (cause) not just that there is a video. I suspect it is the size of the video but I have no idea how to check.
The crash begins with the Windows system stalling - Windows hangs. Firefox then changes to an all-white window. After a few seconds, the text and images return but the video section is black with a warning that it is locked out of the graphics hardware. The laptop also display a notification saying the same (see attached image). Videos will not play until Windows is rebooted. Restarting firefox doesn't help.
I can't be certain but I think that a separate similar symptom is the same problem; Windows stalls briefly from time to time but then comes back after just a few seconds, at most.
My Win 10 system is fully up-to-date.
Checking for solutions on the internet, I have updated the display adapter [Intel(R) UHD Graphics 620] driver. This had zero effect. I have also run System File Checker and DISM commands (as per instructions at https://www.drivereasy.com/knowledge/application-blocked-accessing-graphics-hardware-error-windows-10-solved/). This also had no effect.
I have now uninstalled the most recent version of Firefox (85) 64-bit. I have installed 82.0.3 (64-bit). So far it has not crashed, even when playing the same video that appeared to cause the last crash: the video is on https://returntonow.net/2020/10/12/forest-garden-with-500-kinds-of-food-requires-only-a-few-hours-of-work-per-month/ and it's direct address is https://www.youtube.com/watch?v=6GJFL0MD9fc&feature=emb_rel_end)
I now appear to be stuck, unable to use the most recent version so forced to stay on an outdated Firefox 82.0.3. If anyone can explain how to fix this problem, I'd be grateful
System details in the attached image.
THIS IS ADDITIONAL INFO:
It's been a week and nobody has helped. I am nearing to point where Firefox will be useless to me.
As I scroll past embedded videos, Firefox still stalls, whites out and then the error message is presented telling me the "Application has been blocked from accessing graphics hardware". So, in the hope it would help, I went into OPTIONS, There, I attempted to block autoplay and sound from ALL videos. I ticked the appropriate box in the Security and Privacy tab. That had zero effect, videos still auto-played. SO I went back and unticked, then ticked the box again. that did nothing. Then I repeated that, closed Firefox, reopened it and still videos autoplayed. Then I went into about:config. Then I applied all of the following values:
media.autoplay.default = 5 [0:allow; 1:blockAudible; 5:blockAll] media.autoplay.allow-extension-background-pages = false media.autoplay.block-event.enabled = true media.autoplay.enabled.user-gestures-needed = false
And firefox remains the same, videos still autoplay. What the hell is going on?
