Last night I updated my iPhone 11 Pro to iOS 26.1

Since the upgrade I'm unable to have Firefox play audio for a music stream I listen to when the phone goes to sleep/lock or if I use the app switcher to switch to another app, like Maps.

This wasn't happening yesterday when I was using my phone and listening to the same audio stream in my car with Maps open for navigation.

Hi, how can i disable background playback, when the browser is closed and the screen of the device is off? For example, when I'm watching a YouTube video, then I close the browser and turn of the screen of galaxy s10 ultra, the audio continues playing on the background while the browser is closed and the screen is off. I don't have the kind of problem with other browsers. I tried all of the settings, but didn't find anything in the settings thatt can disable the background audio. The only way to stop the background audio playing is by forced closing of browser or manually stopping the video playback on the YouTube video itself.

Thanks.

This video file cannot be played.(Error Code: 102630)

I’m getting this error for some reason, and I can’t figure it out. I’ve tried downloading various support files for different codecs, yet I still can’t play videos on websites or live videos like YouTube livestreams.

I’ve tried reinstalling the browser, VLC, and updating the media drivers, but it still doesn’t help. The same videos run fine in other browsers like Edge, but for some reason, they won’t play in Firefox.

As of Nov. 12th, 2025 (Firefox Version 145.0 (64-bit)) entering full screen for a video reveals desktop/other program windows.

Tested with different websites, YouTube, Amazon Prime Video and Hulu. Issue is consistent across.

In the images provided there are two sets, one full screen the other not. Set desktop background to bright green to highlight issue.

If it matters, using dual monitor setup (BenQ Mobiuz EX2510) both are 1080p 144hz side and issue occurs on both monitors.

Have already tested basic troubleshooting issues such as restarting Firefox and computer.

Thank you.

This is where you describe the issue in detail.

Explain what’s happening (e.g., “Videos keep freezing after 10 seconds”).

Mention when it started and what you already tried.

Include your Firefox version (you can find it under Menu → Help → About Firefox).

Hi, I am using Firefox Developer Edition though I have had this problem with Firefox in the past. The problem is that sometimes the audio from Firefox just stops working, everything else in Windows works but not firefox, I tried having the same youtube video on Firefox and Chrome annd it worked on Chrome. There are times that a Windows restart fixes it and there are times that I just have to wait a couple of days till it fixes itself. The only thing I could find to trigger this behavior is to have mi Bluetooth earphones connected, then disconnect them and sometimes when reconnecting them the audio is just gone. This usually happens when I am working, when I start the day I put them on and start some music on Youtube, after 3-4 hours I do a 15 minutes break and during that time I charge the earphones, when I come back and turn them on again, most of the times the audio is gone. Is this a known issue or something? I can send anything if you want. Thank you

Hello. For about a month or 2 videos on my mobile browser won't play with sound and sometimes they play without sound. The same situation I have with Brave browser. I tried Vanadium and IronFox and it works fine there. I really don't know what's wrong and how to fix it.

I have a computer with Windows 10 and I connect it to a Samsung TV with an HDMI cable. The image plays correctly, the speakers seem to be Samsung's, but while the Windows sounds are heard correctly on the TV, the sounds from the web environment, e.g. Youtube, are only heard on the computer. What settings can I make in Firefox to solve the problem?
