Firefox 社群討論區

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!

Since the latest update to my Firefox, videos (for example, in documents such as surveys) either do not load or they freeze. And in some streaming applications, either they play with no sound or when sound is turned on the video freezes. This was never a problem until recently. iMac desktop (2017) Ventura 13.7.4 Firefox 136.0.2 (64 bit) The same issue does not occur on Safari or on my iPad (using Firefox). Any advice?? Thanks.

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

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.

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

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.

FINALLY got my zorin os to update, and now also have the newest version of firefox uploaded and working. My singlefile addon works properly, I have upgraded to the newest versions of my video downloaders, and I have cleared my history, but my 2 video downloaders still don't recognize any videos on youtube. Any suggestions or alternative downloaders?

I have installed a analog to digital converter software to convert High8 tapes to digital. It is all hooked up, but the video and audio from the converter program will no show on computer. Help!

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

I have Win 11 dell computer that does not play or pick up sound from web sites videos .I checked and tested my sound using the Microsoft platform & buy playing a disc. It works OK

Youtube brought up in the broswer works fine with audio/video but on other websites I can view the video and can't hear the audio.

Following a recent update of my bios (AMD Ryzen) of my PC the on-board sound system failed. I chased down the issue, got a sound card to circumvent the on-board circuits, and had sound once again but for my FireFox (Ver 133.0.3, on Windows 11 Home, Ver 10.0.22631 Build 22631). Testing with alternate browsers (Edge, Opera) the sound works, as do my downloaded games and music but no joy with FireFox.

My question: Is this a known issue being addressed for a future update or are my circumstances an outlier issue?

My account on thinkific is cookingasmedicine.thinkific.com When I go to the "course" and click on a video whether in my class or one I am taking, the videos will NOT play. I have been talking with Thinkific and we've gone through all the videos of yours and theirs - the settings, checked my updates and nothing works. I have no trouble on my laptop or my Iphone using firefox on laptop just on my desktop LENOVO.

I checked my set up that is on the laptop and made it exactly the same on my desktop but STILL to no avail. The videos will simply NOT play!

Would you please help me?

I have Windows 10 and currently have auto updates so I am up to date with your updates. I just can't imagine what it could be that's stopping the videos from playing? They played perfectly for three years! I have not put any new apps or programs on my computer either.

Thank you, Claire
