Hello, I'm having a problem on Windows 10. It's a fresh windows installation and I tried already some solutions: reinstalling firefox, deleting cache, refreshing firefox, private windows, no add ons, trouble shoot mod. Nothing helped. The problem seems to be with live stream, either on twitch.tv or youtube.

I am running Firefox 144.0 on kubuntu 24.04.3 LTS I have lost sound on Firefox. I have opened the same sites in Chrome and the sound is working fine. It's only in Firefox. I have tried several sites including Udemy, YouTube, and radio programs, no sound from Firefox. The problem started in the middle of a Jit.Si session. All of a sudden the sound disappeared. I thought that restart Firefox would help, then restart the computer would help. But the problem has continued. The speakers is turned on the volume is up, just not a sound from Firefox. What to do?

As explained in the title. On my Galaxy A15, i tested the browser version of Reddit, Youtube, Behance, Instagram and even 4chan. All give the videos as corrupted or stuck on loading.

I already tried cleaning Cookies and site data, the history, already tried disabling all the add-ons, already checked for updates and reinstalling the app. I tested the same websites listed above on Opera and they worked perfectly. Please tell me if there is anything else i should try

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 🙈).

Hello, I did a lot of search and followed all these advises: https://support.mozilla.org/en-US/questions/1229615 https://winaero.com/remove-your-browser-is-being-managed-by-your-organization-from-firefox/

1. I have not entry "DisableFirefoxAccounts" in "HKEY_CURRENT_USER\Software\Policies\Mozilla\Firefox". 2. I have no policies.json file in firefox directory. 3. I have a message "Your browser is being managed by your organization." in "Settings" (about:preferences). 4. In "about:policies" I have DisableFirefoxAccounts=TRUE. 5. in "about:config" identity.fxaccounts.enabled=false and grayed out.

Please help me to turn on the sync of bookmarks. All these listed issues obviously have something to do with it.

When listening to YouTube in the background, sound is distorted and stutters frequently, which makes it pretty much unusable. Audio is okay when Firefox is in the foreground, but as soon as I lock the phone, audio stutters appear.

I found one fix on Reddit, disabling HD sound in developer options, but I was unable to try it since nobody explained how to get to these developer options, I wasn't able to find that setting myself.

It started happening since 135, was in beta as well. I opted out of beta because of it, but it came on stable release as well so now both beta and stable versions has this issue.

Has anybody encounter that or have fix?

For years I have been able to watch a foreign TV website, despite having only a DSL connection (I allow only the scripts essential to make it work). Since I did the last update, to 137.0, I cannot watch either the live stream ("General source error") or old programs ("There is something wrong with your internet connection"). This is absolutely consistent; I've lost count of the times I've tried.

I never had problems like this before. At worst, if Windows was running a background process I might have to stop it to keep from having pauses in the program. All I can think of is that you did something in the new version of Firefox that has made video impossible on DSL.

Hello, after updating the mobile Firefox to version 135, I encountered a problem. When I start speeding up video playback on YouTube, a clicking sound regularly appears, as if it’s a micro-stutter in the audio. I uninstalled and reinstalled the browser, and the issue persists even on a clean browser with no extensions. A similar issue also exists in the beta version of Firefox 136 and the nightly version 137, which I installed for testing without making any changes. To check, I installed Firefox 134 again, and the issue does not occur there. My phone, the Tecno Pova 6 Neo, is relatively powerful with an 8-core processor at 2.2 GHz and 8 GB of RAM. Operating system HiOS 14 on Android 14. Could you help me? Thank you.

Since the last update, I believe, because this error occurs constantly and with EVERY video. This is often, not always, the case immediately after updating FF. Now it was fine for a while, but now it's so bad that I'm having trouble watching YT videos properly. Reason: Browser open, logged in to YT. I click on a video to play - video opens, plays maybe 10 to 20 seconds, then playback stops spinning top, I also found out during the last glitch after update that if I switch the resolution briefly, higher or lower doesn't matter - important is to leave the current resolution and switch to another one. And oh wonder - immediately, instantly with the change, the video starts playing. If I wait for this - without doing anything myself, it sometimes takes 30 - 40 seconds for the video to start ... sometimes it just "hangs" ... This is extremely annoying - if it doesn't work, I have to switch browsers... What is also extremely annoying is that it occurs almost regularly after an update ... until the next one possibly, for unknown reasons, does not fix the error, but sometimes mitigates it. Now, however, the disruption/interruption is so massive and totally annoying that I'm thinking of switching. I'm just tired of it ...

Hi. There is a problem with video playback when skipping through the video using a playback bar. The video (but not audio) freezes at the spot when one skippes to another part of the video and re-establishes after a while (not so short while) to the part of the video that is currently played. I'm using Linux Fedora.
