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 🙈).

!. link to youtube only flashes then plays only audio. Full video requires opening link in a new private browser window

2. Typing into search bar for Duck Duck Go in new tab page types directly into active bar...

3. Active bar is no longer at the top but is in Bookmarks toolbar...

I suspect some update problem.

Media resource could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_DECODE_ERR (0x806e0004) Details: virtual mozilla::MediaResult mozilla::FFmpegVideoDecoder<62>::DoDecode(mozilla::MediaRawData*, uint8_t*, int, bool*, mozilla::MediaDataDecoder::DecodedData&): avcodec_send_packet error: Unknown error occurred

Fire fox is automatically playing videos/sound or both if I click on a tab that has that or also in facebook, etc. How do I stop this? I want to be able to click play when I want to hear/see something.

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.

I have Win 11 dell computer that does not play or pick up sound from web sites videos .I checked and tested my sound using the Microsoft platform & buy playing a disc. It works OK

Earlier today the audio on Firefox stopped working. I have tried disabling extensions, checked output devices, reinstalled and it still doesn't work. Please Help. The Version is 150.0.1

Browsing this website article I can see that there are embedded Youtube videos in the article but they are not loading, instead I only see blank spaces. I've turned off all extensions, turned off tracking protection, cleared cache and cookies for both the website and Youtube.com, and tried viewing the website in troubleshoot mode.

YouTube videos encoded at 60 frames per second are extremely choppy in Firefox only. Microsoft Edge plays the same videos perfectly.

I have deleted my profile and reinstalled Firefox, updated graphics driver to the latest version, and toggled hardware acceleration on and off. Nothing helps.

When I open Facebook in Firefox 150.0.1 with no extensions then move the cursor over a video, that video automatically plays.

Preferences | Privacy and Security | Browser Privacy | Permissions | Autoplay | Default is set to Block Audio and Video yet videos still automatically play.

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.

how to cast videos from my phone to my TV if I got android phone, and I have i basic Sylvania TV without wifi or Bluetooth connection, hmi and a softwaode with fire fox app.link text

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.

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.
