Firefox Community Forum

I swear this used to be a setting and it vanished or i'm blind. say you open a youtube video in a new tab while staying on your current browsing tab, it used to auto-pause in the background until you navigate to the new tab. I remember being so happy when i found the setting, and it stopped working recently so i went looking for it. it doesn't exist. send help.

After updating firefox from 128.8.0 to 128.9.0, no embedded videos will play (youtube, instagram, plex, etc...)

The only way to get them to play is to run the browser in troubleshoot mode. Even a fresh browser profile doesn't work. Disabling hardware acceleration also does not work. Tried firefox 137.0.2 and that also does not work. Downgraded back to 128.8.0 and videos play flawlessly again.

I'm running firefox on gentoo linux on a thinkpad x13s (arm64) which uses Qualcomm Adreno 690 graphics.

Anything I should try would be greatly appreciated. Thanks.

Just built a new PC and using Win11. I like to have a pinned tab in Firefox playing some kind of media to have background noise. Since new build, whenever I am not 'focused' on that tab and doing other tasks, audio from that tab will cut/fade in and out.

I've been working on this for 16 hours. I've googled, binged, even yahooed. No answers. Checked and rechecked all settings, both system and browser. Uninstalled/Reinstalled *many* applications, including Firefox. My OCD won't let me rest till I have this solved.

Thanks for the help.

i cant get in my you-tube for watch full movies and tell me about DRM and then that Firefox is installing components need to play the audio or video on this page.i need help to fix this

Hello, I’m using Mozilla Firefox on Windows 10.

The issue happens mainly on YouTube: – Videos stutter every few seconds – Audio sometimes goes out of sync – This happens on 1080p and 720p – My internet speed is stable (~XX Mbps)

When I load the video the page loads like normal, all comments and everything is there except the video square is not there. cant see the video, anyhow. even if i move my mouse cursor on it on the start page, the little video wont play the preview. no video player at all. anywhere.

Hello! from this morning and alongside a new Firefox update i've been having graphical artifacts on Youtube/Facebook/Netflix. I've followed all the standard steps.

Disabled Hardware Acceleration. Updated Video Drives. Run FF in Safe Mode without plugins. Disabled Router level VPN and Ghostery.

Any ideas?

I'm running FF135.0 Geforce 572.16 Drives (30th Jan) 3070TI. Windows 10 Pro 22H2.

no matter what I try I cannot get any content from HBO max, crunchyroll, or spotify to play. I feel as though I have tried every troublshooting step. In firefox 140.0.4 64 bit on windows 10 I have:

-turned DRM off and on -disabled and re-enabled widevine -disabling all extensions -try in a private tab -turning off tracking protection -clearing cookies/cache/site data -uninstalling and reinstalling firefox -trying on firefox nightly -trying on other firefox based browsers zen, librefox same issue. chromium based browsers and firefox on my windows 11 laptop play drm content like normal -manually installing older version of widevine -changing useragent to chrome(this triggered cloudflare and would not let me pass) -making another user in windows and trying there

the error i get on crunchyroll is code: DRM-0 and on spotify it loads but the play icon does nothing. in hbo max i get error code 1k-0003

At this point I don't know what else to try, If there is not another solution I probably try to just switch to brave browser or wiping this pc and reinstalling windows.

I've noticed that whenever I press ⌥⇧Space (option-shift-spacebar) in Firefox Developer Edition, it causes the page to refresh.

This behaviour seems to be consistent across devices.

Is there a way to change/disable this behaviour? It is very inconvenient, as it often causes me to accidentally trigger a page refresh when I type an em dash (`—`) in a text input (opt-shift-dash, and then type a space character after it, I'm very likely to hit opt-shift-space by mistake 🙈).

Since to your "upgrade"to firefocx on my computer I can no longer watch youtube or iplayer videos. Pease say how I can downgrade my version so as to be able to see these.
