Firefox Community Forum

For the last maybe 2 weeks of so I have been able to play videos on any website,it is only Firefox that is having the errors. I use Windows 10, and the only extension I have is password managment

I have tried: 1) troubleshoot mode: no changes 2) clearing cache: no change 3) making a new Mozilla profile: no change 4) lowering/turning off security protections 5) refreshing from uninstall 6) uninstalling and reinstalling 7) Allowed autoplay of media 8) toggled off drm

The primary sites that I use are; HBO - error 1K-003 Twitch- error#4000 Patreon- doesn't error out, but just goes black on player Dropout.tv- player error YoutubeLive- Browser error

audio stops completely for exactly 0.4 seconds when un-pausing video, this affects any "interruptions" including skipping around, clicking on timestamps and any ohter type. issue stops completely when another youtube tab with a video playing is currently active.

i have tried any regular troubleshooting tips, including any and all forums i've found online to no avail. this is not happening in any other browser.

Whenever I try to full screen in any streaming websites, it's not full screen at all. There is a little bit of space in the left-side and top-side of the screen where the other windows or applications I have can be seen (or my desktop if nothing else is open). This is not happening to other browsers. Can you please help me to fix this?

Hello, I hope you are well.

All videos played on my FireFox browser are slowed. This happens on any video playing, including on YouTube, even when the video is on 1x speed and is not slowed. It has been getting progressively slower over the past months, and was not fixed after I uninstalled and reinstalled FireFox. Please kindly assist.
