Firefox コミュニティフォーラム

Hello, this is the basic problem:

The short version is that there is a problem with Firefox not interacting with the scrub bar and volume bar. (all other controls work fine) We know it's a Firefox thing because everything works with Brave. (or an interaction between Firefox and the OS at least, Firefox is heavily involved)

There is more detail and we have done some work on it here: CashyOS forum post

You can use the Firefox manifesto V0.2. video for an example, as it displays all the above problems for me.

I can get you guys whatever other data might be needed, but I kinda need an idea where to look to try and fix this, as all the other posts I have managed to find don't seem to have similar enough issues to work.

I am trying enable autoplay for website https://www.citiprogram.org and cannot find a way despite instructions.

Good afternoon

recently i tried just realise my firefox can't played HEVC streaming video like twitch etc. (1st pictures)

i check on other browser such as Chrome, Edge, etc. it's played normal i check on google all about config

like media.wmf.hevc.enabled , media.hevc.enabled , dom.media.webcodecs.h265.enabled all set to true. checking on about:support i found it's not supported (2nd screenshot)

i check on Powershell are like this :

C:\WINDOWS\system32> Get-AppxPackage | Where-Object {$_.Name -like "*HEVC*"}

Hello,

I am having trouble with my Simple Practice connection static and video not functioning for my sessions with clients on Firefox and would like to have this remedied...Maybe I just need an update but looked under Settings and didn't see that option. Please advise. Thank you!

Since yesterday, videos on NetMirror are not playing. Every video shows a “Video load failed” error. I have tried multiple times, but the problem is still happening. Please help me fix this issue.

My Youtube video stutters every 6-10 seconds. When I turn off my HW acc off, this issue happened. Turning the HW acc on solve it, but the thing is if I have my HW acc on another problem came up, which is my Firefox will starts to blink. Anyone has a solution for this?

firefox has always been the brower i choose .

but lately firefox is unable to browes or play streams

i tryed all online steps to have it resolfed but still nothing

after 8 hours of youtube.com videos of the chosen video stopped 30 minutes before end how do I prevent broadcast from stopping in middle of video; is there a memory issue or function command to extend broadcast or notification when near limit

I play videos in full screen mode everyday using Firefox. Recently when I move away from the full screen application to a different open window then the taskbar at the bottom of the screen does not appear. I just attempted to duplicate the issue and take some screenshots only to find that if I'm switching to a second Firefox window the taskbar does not show, but if I switch to a file explorer, or Excel Window then it does show. This makes things very difficult because I'm using the Snipping tool to take screenshots, and the Snipping Tool itself allows the taskbar to display.

YouTube videos are playing choppily in Firefox. The video frequently stutters/freezes or does not play smoothly, even when the same videos work normally in another browser. I have restarted Firefox and my device, but the problem continues. I would like help identifying whether the cause is hardware acceleration, Firefox extensions, graphics drivers, or another Firefox setting, and I would appreciate step-by-step troubleshooting instructions.
