Good morning from germany,

I am a multiple year subscriber and wanted to watch game 6 before going to work (it is around 6 am over here) but the player isn´t running and it states that games can not be played, even the recap doesn´t start. Other videos are running as on youtube and other social networks. I switched a VPN from location germany to location USA to off but nothing works. I am using the newest version of mozilla firefox.

Can you give me some help what I can watch in order to watch the last two Finals games as well?

Thx guys

Status bar not hiding in fullscreen video after updating to Firefox 138.0.1 (64-bit) on Windows

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!

Starting today, YouTube on Android Firefox using below version of Firefox, the audio distorts and has a continual popping clicking on each word of an audio podcast when you speed up the YouTube video to 1.5 or 1.75 prior to today it was fine ... The audio is still understandable but distorted when using one of these speed up settings

Using the Chrome browser, everything is fine on the speed up settings on YouTube.com

I've been searching for an answer to this for weeks to no avail. It concerns YouTube videos "autoplay"ing on YouTube. Many have asked this question and most responses state to shut off Autoplay. These are two separate issues. AotuPlay means the next video on YouTube will advnace automatically requiring no user input. If Autoplay is off, streaming stops at the end of the video. The issue I am having is when I open a YouTube video to a new tab (but do not switch to that tab), the video WILL start playing as soon as that tab is in focus. This never used to happen and indeed, on two other computers with the settings and extensions all sync'ed, this doesn't happen, except for on this one computer. Today I found someone that posted the exact same problem 5 years ago and didn't get an answer. He seems to describe it well:

  1. Okay, so before, when I loaded up 100+ Youtube videos, they stayed when switching tabs - no autoplay. Suddenly they decide to autoplay when switching tabs - note, I've not done anything to my settings or plugins. Fair enough, maybe you changed something (which you often do, without informing). So I check the options. It was on "Block audio", which obviously didn't work, so I tried "Block Audio and Video" - which WORKS, but now both the video is paused (which I want) AND the audio is set to mute (which I DON'T want) - so... what does it take to have Youtube wait for a click to start playing a video loaded in a background tab, but KEEP AUDIO ACTIVE, so I don't also have to unmute the damn video?

One person posted a possible solution: Maybe check this pref on the about:config page.

   media.block-autoplay-until-in-foreground 

This setting describes the issue kind of. If you have this set to false, the moment you send a link to a new tab, YouTube starts playing in the background. Setting it to false keeps the video paused until that tab is in focus. That is how mine has always been set. What I am looking for is a setting that would say something like: "block autoplay until play is pressed"

Thanks in advance and sorry for being so long-winded

So, my problem is with HW acceleration in FF. Basically:

If its enabled: It causes graphical artifacts in videos [See screenshot]. If its disabled: It brings screen tear in to videos and autoscroll [Like if Vsync is disabled in games].

I tried safe mode, I tried reinstall of FF, I tried disabling and enabling extensions. I tried to set Vsync on in Nvidia control panel... the only thing that impact those bugs is HW acceleration in FF.

My drivers are up to date, my browser is up to date, yet there is such trouble.

Any ideas or solutions?

When I play a video with the web player in Firefox that has AC3 audio, I get no sound.

Doing some research it looks like AC3 used to be patented so I assume that is why it isn't included in Firefox but since March 20, 2017 the patent for AC3 has expired so I'd think it's now OK to include in Firefox.

The same video works in Edge and Chrome.

I'm looking for a solution to an annoying bug in Firefox on Windows 11. The taskbar won't hide when I go into fullscreen on videos (e.g. YouTube).

The issue is directly tied to hardware acceleration.

This doesn't happen in Chrome, and I've already tried reinstalling Firefox and updating all my drivers and Windows. Does anyone know of a fix for this bug?
