I updated to Firefox v155 today and noticed immediately that video is washed out. Please see attached image. Firefox is on the left and Safari is on the right. I haven't updated my laptop yet and video looks 100x better.

For the past month, out of the blue, I have been unable to play Spotify via my web browser. After troubleshooting with Spotify chat, it seems the issue is actually Firefox, because if I choose to play it via the app installed on my computer, it will play, but not via the web browser.

It was display "Spotify can't play this right now".. then it will skip through three songs, play ads & then will play the first 10 seconds of audio of the next song & then it will cut out.

Anyone else experiencing issues with Spotify via the Firebox web browser?

this exact question has been asked last year, none of the suggestions work: I am running Firefox 154.01 on Winux I have lost sound on Firefox. I have opened the same sites in Chromium and the sound is working fine. It's only in Firefox. I have tried several sites including , YouTube, and radio programs, no sound from Firefox. All of a sudden the sound disappeared. The speakers is turned on the volume is up, just not a sound from Firefox. What to do? Right now I had to switch over to Chromium

FF dev 155.0b5 (but this has been ongoing for 1+yr). W11p. Is there somewhere in settings where I can "disable" whatever is blocking videos from being seen? (for example BBC news videos). I have to go to troubleshoot mode to watch. I have previously disabled all potential blocking exts like ghostery & UBlock, but to no effect (still no videos). I have looked in security in settings. Otherwise, I either go to troubleshoot or open chrome. Or, is there an extension that will allow that video viewing? Please advise, thank you.

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

Hello All,

I have a somewhat confusing issue that I've only found two posts on Reddit mentioning previously, but there were no responses.

A short summary: On Discord's website, in an audio call, audio will progressively move from stereo/both ears to mono/only the right ear after anywhere from five to sixty seconds. This only occurs on Firefox, it does not occur on Chrome or Edge (with the same extensions, when applicable.) For the record - this also only occurs with the one headset. I've tried with a second headset and don't have the same issue, but I don't believe the Headset is solely to blame since the issue only happens on Firefox.

I have also tested on Firefox Nightly as a fresh install - no extensions, no settings changed, just install and login to Discord.

Specs:

ASUS TUF Dash F15 FX517ZR HP USB-C G5 Essential Dock (Monitors are connected through it) Windows 11 (August update/build 26200.9168) Razer Blackshark V2 Pro RZ04-0453 headset (Connects via USB-A Dongle plugged in to the laptop) Firefox (x64) (154.0.1)

Troubleshooting steps I've taken:

Removing the Audio driver for my computer and re-installing it. Removing/re-installing the drivers for the Headset. Verified all audio related drivers for my device are up to date. Verified the BIOS is up to date (it's solved unusual problems before) Toggling the "media.latency_preference" toggle in about:config (recommendation from a friend) Disabling all extensions on Discord. Disabling Firefox's strict mode on Discord. Verifying all audio related drivers for my device are up to date. Tested on a Firefox Nightly install (the first time it's been installed on my device). A separate browser (Chrome/Edge - the issue is not present) A separate headset (Issue is not present) Downloading Razer Synapse and disabling any "extra" features, and testing with various options on/off. Disabling any and all other Audio devices (speakers and microphones) while using the headset. Charging the Headset to full.

Things I haven't tested, but thought of:

Resetting Firefox in any capacity - I can, but hopefully testing with Nightly is sufficient. A different computer entirely - on my list, when I can next. A new User profile. Testing with no headset at all, and just utilizing the built-in speakers/microphone for the laptop.

Oddities:

Changing audio settings in Windows will "fix" the issue momentarily - for instance the "Spatial sound" option. Changing from one setting to "Off" (or vice versa) fixes the issue for the same ~5-60 seconds until it slowly goes back to the right ear. These options are present for every device, even ones not experiencing this issue.

It's very odd to me because on one hand it may be the headset, but then the issue is only present in Firefox.

Any help or things to test would be greatly appreciated!

Thank you.

Since I updated to Firefox v154 (on Windows 11 w/latest updates) Substack videos freeze at random times 15-30 minutes into playback (never right away). If I close the tab and reuse the original link, playback resumes more at less where it froze, but this is very annoying and happens almost every video. Other online videos (e.g. YouTube) don't seem to have this problem -- but I rarely watch hour-long videos outside of Substack, so I can't confirm that the problem doesn't exist elsewhere. This only seems to occur after streaming 15+ minutes so probably a subtle bug.

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.

I am getting a sharp and loud buzzing sound when I watch Netflix on my Firefox browser, and today, it started doing the same on Facebook reels. I don't have that problem in Edge so clearly, it is a Firefox issue. Thanks for getting back to me to let me know if you can resolve that issue, or if there is anything I should be doing. Kind regards, Isabelle

Hello, I am hoping someone can help me. I am getting white pixels/lines during youtube play back. There is only ever one at a time. I do not get it every time I watch a video. The lines move with the player if I move the browser.

I have tried: Updating Firefox/drivers Turning Hardware acceleration on/off Setting Firefox to use the dGPU Changing the Optimus mode

I am using Windows 11 and have a Legion 7i Pro Gen 8

I have uploaded an image that shows the line. The line appears in the grass on the right.

Many thanks
