Firefox Community Forum

Hello,

I recently updated my Firefox browser to the latest version, 138.0.1 (64-bit), on Windows.

After the update, I noticed that when playing videos in fullscreen mode (for example, on YouTube or other video websites), the Windows taskbar (the bar at the bottom of the screen with the Start menu icon) does not hide automatically. This is affecting my fullscreen viewing experience.

Before updating to version 138.0.1, the Windows taskbar would hide correctly when entering fullscreen video.

I was wondering if anyone else has encountered a similar issue with the Windows taskbar not hiding, or if there are any suggested solutions to help resolve this problem.

Thank you for your help!

This issue just appeared. Video will not play in Firefox. Windows10 PC, up to date with latest versions, as is Firefox. There is no error message or code. Just the spinning wheel. I see other people are having the same issue but I haven't seen a solution. Any ideas or help appreciated.

Initially connects video playing to Headphones via Bluetooth then audio stops. Reloading doesn't help. But the same works perfectly on other browsers. Problem is with Firefox audio setting. The problem started only a week ago for firefox

Can't seem to stream Netflix. Firefox is up to date. New Widevinecdm update today 4/2/2025. Apparently since that update (today) I can't stream. I get Netflix error code F7702-1003. Searched/read several FF articles/forum Qs - no help. did a "refresh FF" - no help. don't want to install Chrome (Google knows too much about me already). Netflix worked fine last night. Tried unchecking "play DRM controlled content" - FF(Netflix site) asked to enable DRM - clicked ok - reinstalled. no help. Hard reboot - no help. Still running a Win7 64-bit desktop OS - works fine.

HELP!! Thanks

Hi there..! Some days ago my firefox browser became somehow "muted". There is no sound. I uninstalled it and installed it three or four times but no sucess. Using another browsers there is not such a problem... Any idea ...

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.

Having issues with my Bluetooth AirPods and sound in Firefox. The problem being there is no sound when the device is connected and watching a YouTube video for instance. Things went wonky after the recent update to 133.0.3. At first there was no sound period. Then somehow, not even sure how, I saw that Firefox was muted in Windows (11 Pro) settings. That's a mystery unto itself since I'd never previously gone to that area. Now that I have volume through external speakers working, audio through AirPods doesn't. Everything works fine using Edge and audio from music. I know the device is connected and when that is, it's the default for where sound comes from. Used the test thing and yup there is audio. Is there something I'm missing? There must be but I can't figure out what it is. Hopefully someone reading this can point me in the right direction of resolving this issue. Thank you in advance.

My GPU is the integrated GPU on the Intel U7-155H CPU. When some AVC videos are played, the browser reacts extremely slow and the video image is glitched and at a really low rate of frame, and the video decoding engine seemed to be 100% occupied as shown in the task manager (normal video playback never occupied so much of it). Seems like AV1 encoded video never triggered the problem. The problem doesn't always happen, but at a rather high frequency. This never happened before I updated the Intel graphics driver from 32.0.101.5972 to 32.0.101.6129. The problem seemed not to happen on other browsers such as Microsoft Edge.

Yesterday my audio on Firefox worked, today it doesn't. I tried all the regular trouble shooting solutions. - My system volume is not 0 - My tabs aren't muted - My headphones are turned on and working fine (audio works everywhere but Firefox) - I uninstalled and reinstalled my Firefox - I uninstalled and reinstalled my headphone audio drivers - Audio also does not work in a private browser, so I know the issue it's related to extensions, cookies, etc. - I had Windows 11 do a quick diagnostic, so the issue isn't Windows 11 related

Usually when this issue occurs, it's as simple as switching from "default" to a specific speaker in volume mixer, but Firefox is not appearing in volume mixer like it did in the past, as shown in the screenshot below.

I don't know what else to do at this point. In previous documentation here, the solution for some people was to wait and it eventually fixed itself, but I'd rather not have audio for weeks to months on end, so has anyone found another solution by chance?

There used to be dozens of video downloaders. Now, none of them work except for one that requires a ridiculous fee. Are there still youtube video downloaders that still work

Dear Jim,

I needed to go to sleep at 3am last night to rise for a 12 noon Christmas day dinner. So I am back now.

I have not been able to drag a picture into the text of an email message.

I mark the point of insert with the cursor, go to Insert menu, select the attach picture, and it ends up at the top of the email outside my message. When I try to drag the picture into the text area, a mat covers the text area instructing to insert it here. When I release it on the hotspot, the matted area goes blank and I receive a menu message "The following files couldn't be attached: "filename.jpg". Please try again later."

I seem to be doing everything correctly. I was able to do this some time in the past.

I am wondering if the problem has to do with a memory cache problem. Do I have too many 2000 blocked emails. Maybe a security problem not allowing the attachment?

For many years, I have been exchanging video calls on Facebook.

Recent attempts to video call the same person I've been video calling for the past 3 years result in "your browser doesn't support video calls"

Have I been "hacked"?

Please explain.

Could a real person answer this question for me, please? Thank you.
