Gifv will not load
The problem: - Gifvs on certain websites like twitter will not load, and when I inspect it, it says:
"Media resource XXXX.mp4 could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_DECODE_ERR (0x806e0004) Details: void mozilla::AppleVTDecoder::OnDecodeError(OSStatus): OnDecodeError:ffffcd9a"
- Other html5 mp4 videos work normally. - Same gifvs work normally in Safari.
Things I have tried: - Clear the cache and cookies - Open the page in a private window with no extensions - Allow autoplay - Set image.animation_mode to normal - Restart in troubleshoot mode. This is the weird part: gifv does load in troubleshoot mode, and then if I simply restart firefox in normal mode, everything works fine magically (for any website). But it only lasts for a few hours, the next day it will break again.
Firefox version: 89.0.2 OS version: macOS Catalina 10.15.7
Any thoughts on what goes wrong?
