!. 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.

Reposting until I get help from someone. Windows/desktop. On Google Chrome, any streaming website I used with autoplay enabled would KEEP full screen mode ON after changing episodes. It would automatically go to a new page with the following episode and remain full screen. Why doesn't Firefox have this feature?? I'm seriously considering going back to Google Chrome for this one small feature. Every time I had any streaming service playing with autoplay enabled, I didn't have to manually select the full screen option every time. I am having to stand up and manually click full screen function. Every. Single. Time. Somebody please help me if there's a way to active that function.

For a couple of days now Instagram linked videos won't play here. Actually some of them will -- my own reels and anything linked with that button that looks like a movie 'clapper'. But videos that show the triangular arrow pointing to the right, nothing happens when you click. Not sure if this is a FF issue or maybe something changed at Instagram. Did a google search and nothing came up.

This is a functional bug, not a settings issue. Block media autoplay in Firefox cannot work, after I right-click on a blank area of the page and scroll.

For example, I saw a post with a video on x.com, and the site was set to prohibit automatic video playback. But when I right-clicked on the webpage and then scrolled the page with the mouse, the video started to play automatically, which means that the function of prohibiting video playback was invalid. Very strange.

Firefox version: 141.0.3 (private-browsing No extensions are running) OS: Windows11 Enterprise 26100.4946

Sound on Rumble. It has always had an Enable Button with a bell, and clicking on that button has always enabled the sound at the videos I watch on Rumble. Recently, clicking on the button, adjusting the sound on Rumble settings in the video, and boosting the sound on my computer do not work. I'm hoping that can be fixed. Thanks in advance.

Firefox is no longer playing audio from the Internet. I am running Firefox on Windows 11, and have the latest update installed (10/29/25). What happened? How do I fix this.

I am 99.5% sure this is a Firefox issue, as I have no problem playing audio files stored in my computer, and no problem playing Internet audio using Chrome or Edge.

Help!

[redacted] problem you [redacted] im having issues with the video and ads as all of my apps are disabeld nothing works and firefox it self causing probs and no one is helping out.

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 🙈).

Only on firefox, the music on apple music keeps changing volume. I can hear it sound fine for a second but then it changes the volume to around half of what its meant to be. I dont see any settings to change it, its fine on other browsers, im genuinely unsure of what to do.

Bug in FireFox ... gives me a blank screen when trying to access this link : https://harrisonburg.org/music_scene/song_list/songs/Werwolves_studio.mp3

Has worked well for years, but with updates you broke it.

When I play YouTube videos in Firefox, the video stutters and drops frames, even when set to 480p. The audio continues to play normally. This issue does not happen in Chrome on the same laptop.

The problem started about a week ago. I’m using Firefox on Windows 11. Restarting Firefox did not resolve the issue. I’ve attached screenshots for reference.

Hi,

How can I force Nightly to play a media type ? Per instance, the top main video here : https://www.lapresse.ca/international/asie-et-oceanie/2025-12-23/coree-du-nord/kim-jong-un-inaugure-un-complexe-hotelier-dans-une-station-de-montagne.php

Best regards iBenny

I am feeding my radio station into my computer, but when i bring the station up on a computer is is a page with my station on it and click on the play button it plays your music instead of my station. How do i fix that?

Since Flathub list the org.mozilla.firefox app as official, i hope this is the correct support channel.

Recently i switched from distro specific package managers to flatpak as my application provider. The firefox flatpak won't play most embedded Video/Media on applications like in-browser fediverse clients, forums, blogs or wikis. Youtube works without any issues, Twitch is fine until there is an adbreak. Then it sometimes stops with the supported format/mime error (screenshot appended), only recoverable by cache-dismissive reload.

I used this Article https://support.mozilla.org/en-US/kb/audio-and-video-firefox and the links it contains to debug without any success. None of these samples play. just shows supported format/mime error https://test-videos.co.uk/bigbuckbunny/mp4-h265 At this test website 1. and 3. example won't play. I provided a screenshot before and after trying to click play on all the examples. https://www.tekeye.uk/html/html5-video-test-page

Contrary to the observed behavior about:support#media claims Software Decoding supported for everything except HEVC.

Chromium Flatpak has no such issues. So i copy the video url and play it with chromium. You can see: dire times.

Good day, I have Firefox 138.0.4 running on Windowx 11 24H2. PC details as follows: CPU = Ryzen 5 2400G RAM = 32GB GPU = RTX 3060Ti 8GB Connection is 50/25Mbps fibre connection

My issue is that when watching F1 from the following site: https://f1tv.formula1.com/, after some time (it differs in how long it takes to manifest), the stream starts to stutter. Note, it is NOT buffering, it is like the stream gets "stuck" or freezes for an instant then continues. The "freeze" then becomes more frequent and sometimes even lasts for about 2 seconds before resuming. The most important fact about all this is that this does NOT happen when using Google Chrome, hence my suspicion that it is somehow related to Firefox specifically. Does anyone have any idea what is causing this and/or how to fix it, please?
