I have a Microsoft Surface Pro 8 with a Slim Pen 2. I do a lot of searching in google maps and have noticed that I can access google maps and can use pinch to decrease and expand the maps and if I open a street view I can use touch to move the field view around as it should be. The problem occurs is when I use my slim pen. Once I have used the slim pen to move a field or open a street view the touch capability stops working. I can still close the window and other things with the touch capability (system type functions), but within the browser it's disabled.

I have not noticed this occurring in any other web site or type. For example I can go to amazon and interchangeably use the pen and touch capability without issue.

I have tested this in Google Chrome and MS Edge and it does not disable the touch capability when I use the pen.

Firefox will not play video from a website. If I save the video, it is a MP4 file. Windows Media Player and VLC will play the video file. But the browser shows the message: "No video with supported format and MIME type found."

Chrome and Edge will play this video correctly in their browsers. Firefox will not play the video on 3 different computers, and even when a different user account is involved (without Firefox sync).

The evidence seems to point at firefox. The website is a Wordpress site.

Is it possible that the website is the problem? If so, why do Edge and Chrome work?

I uninstalled Firefox (latest version) and reinstalled it. Not fixed.

My windows updates are current, as are Dell updates.

This is stumping me. I hope someone can help.

This issue came up in early April 2025.

Programs other than Firefox (e.g. Edge, Media Player) behave normally: when playing sound, if nothing is plugged into the 3.5 mm jack, the sound comes from the desktop's external speakers; and when an audio device (speakers or headphones) is plugged into the 3.5 mm jack, the sound instead comes from that device.

Where as Firefox will play using the internal speakers as expected, but when a device is plugged into the 3.5 mm jack, no sound signal goes to that device.

It seems then that the hardware is okay, and the problem must lie within Firefox, or within a Windows setting that is very specific to Firefox.

The sudden onset earlier this month may point to either a Firefox update, or (less likely) a Windows update.

I´m currently working on some courses in Udemy and all of a sudden the videos are not loading, is not my internet connection I deactivated all the extension to see if it was the case but nothing seems to be working

Hey team,

I am using Firefox 136 browser and browsing my browser sound suddenly has disappeared. The PC sound is just fine with other applications, even with Opera browser I tested. Help is needed.

Audio doesn't work with Firefox. This appears to be ONLY a Firefox problem. Headphones work with Edge. Computer speakers work. In Windows settings, testing audio works. But when I attempt to listen to something in Firefox, there is no sound at all.

I am using Firefox on gnome desktop on the PureOS variant of Debian. About three days ago, I went to listen to my Spotify playlist on Firefox, not through the Spotify app. I had no sound, checked my system settings and turned the volume for Firefox from zero back up to normal. The rest of the song played, but when the next song came on, again no sound. I watched the sound settings and when the song finishes, Firefox disappears from the sound settings list. When the next song starts, Firefox is back in the list but volume is set back to zero. I suspect this may be something in gnome, but I thought I would check here in case anyone else is seeing this issue. Thanks so much for any help or at least a shoulder to cry on :D

I have no idea how to access the following directions I found trying to address the question of : How to stop videos from following as you scroll down a link huff post …..Firefox 135. Mac 12.7.6

Go to about:config and set media.autoplay.enabled.user-gestures-needed to false to disable all kinds of autoplay.

I decided to download Firefox and make it my default browser, so I downloaded it and followed some recommendations I found online for configuring security settings...but for the life of me I can't remember what those are.

Weeks later, I decide to watch Peacock, but the error message says I need to disable my ad blocker. I search for an ad blocker in the extensions but can't find one, so I start disabling other extensions like Facebook Container...but to now avail. I follow all the usual online steps--clearing my cache, restarting the application, restarting my computer, etc--but nothing works. I have the same error with Netflix, and switching to another browser yields the same result. So it must be something wrong with my system.

Can you help?

Video files won't play on the msn.com website; the same videos will play on another browser, but not on Firefox. What do setting I need to change?

Thank you.

My Firefox browser has been crashing for a while now (Years). It's fine playing YouTube and BBC iPlayer but when I advance the time marker to a different part of the stream or video, it crashes. It also has a problem when playing slots. It seems to crash a lot making it impossible to play.

I have tried using Firefox in Troubleshooting Mode but the same things happen.

Here's the crash report ID

Many thanks in anticipation and I hope someone can help me fix these issues.

I'm facing this problem of sound disappearance. I was casually browsing on YouTube when suddenly my sound went off. I thought maybe it was the internet but no everything was okay I also checked my speaker it was ok. Then I found out Firefox was unable to generate any sound. I tried to re-install but didn't work. Can you give me a solution?
