Diễn đàn hỗ trợ Firefox

Each time a video call comes in, the message on messenger, says Video calling is not supported on this browser. I've gone to the browser settings and cannot find anything that would change this. Help.

Hello,

I am having an issue with my Bluetooth headphones (Sennheiser HD 450BT) in Firefox on Windows 11.

The headphones are properly connected to Windows and work correctly with other browsers (Edge, Chrome).

Windows shows the headphones as the default output device (stereo), and test sounds play through them.

However, in Firefox, the audio does not go through the headphones. Instead, it plays very loudly through the laptop speakers.

The problem started today; there were no issues for about a year.

I have tried reconnecting/reinstalling the headphones, but it did not help. Drivers are also up to date.

Could you please advise how to make Firefox correctly use my Bluetooth headphones as the audio output device?

Thank you for your assistance.

i cant play sound from firefox ive tried restarting my computer, disabling my adblocker, everything i can think of its not my headphones, they work fine with files on my computer im having the same problem with davinci resolve too please someone help i dont know what to do anymore

Since I updated to Firefox 141.02 I have not been able to play videos on Paramount+ or Netflix. I get an error on the top that says the Widevine plugin has crashed on both streaming services. I have checked that the plugin is on and there are no updates. I am on Ubuntu 24.04. Video on YouTube plays as normal

As the title says. I get this prompt on videos from different, yet particular websites and sources. And they fail to load. It's also happened where some video's work and some don't, side-by-side on the same website and session.

• I've tried clearing all of my cached data, my browser history, cookies, site-data, settings, and fill-out information. No avail.
• I've tried disabling all of my extensions and add-ons.
• I've even tried using google instead, but I just get constant loading on those particular video's with no thumbnail (As depicted in second picture).
• I've checked my video drivers for updates.
• I've tried reinstalling Adobe Flash Player, even though it says it's no longer supported.

Since it also might be happening in another browser. I understand how this might not be Firefox's fault. But I'm hoping you'll be able to help me still.

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.

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).

For a few weeks now, the bluetooth sound drops out or will not connect, the screen freezes and says Firefox is not responding, the screen buffers for a while. V annoying and only when connecting bluetooth sound. Have tried with two different brand speakers, same thing happens. The bluetooth keyboard does not drop out at all, ever. Image is while listening to a TV series on Hulu~

When I play a downloaded video that is in English, my downloaded file plays back in a foreign language, not English. What am I doing to cause this and how can I have the English version only in playback everytime? Thank you so much, being a pensioner I am eager awaiting the ability to donate to you excellent work as often as I like.

Hi Team

I am facing 2 issue as below.

1. The issue the when I play the video on 2x in YouTube then video and audio both stats lagging.

2. When I am watching any video on YouTube in firefox and minimise it and again open the browser then is open in landscape mode although my auto rotating in off.

There are these 2 bugs which i have found.

Rest are Awesome you are doing great work.

Thank.
