I-Firefox Community Forum

when I hit full screen in the lower left on youtube videos it says full screen unavailable on all videos. I have tried all the recommended setting adjustments in the config and they don't work. yet full screen for youtube videos works in all other browsers on my mac which is an M2 pro macbook pro running sequioa 15.7.4

Please fix this as it is really annoying and I may stop using this browser if it is not taken care of. It just started yesteday out of nowhere. No changes were made on my computer during this time.

The sound works for me on Opera (PC Win11), but not on Mozilla - I see it as a bug in the browser... even after clicking on the playback device in the bottom right corner in Mozilla, the sound doesn't start playing...

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’ve been having trouble with choppy YouTube videos in Firefox. It happens on both Wi-Fi and Ethernet connections. My system is running Windows 10, and I’ve already tried disabling hardware acceleration and clearing my browser cache. The issue persists even when I’m in Safe Mode. I’m using the latest version of Firefox (XX.XX). Any suggestions on how to fix this?"

i have no sound in firefox ,while other applications and edge or chrome give me normal sound.It ia no muted ,checked the volume mixer everything should be working but no sound

Whenever I try to full screen a Youtube video a large solid white bar will appear on the bottom of my screen. It doesn't block the actual video or even the controls but it seems to push the entire video upwards. It only does this on firefox and only on youtube. It seems to be a solid empty space as I can't click on it and right clicking just gives me video playing options. I've tried restarting my computer and firefox a few times and that didn't work. It does however change size and with the browser zoom and color mode respectively. please help.

Hello,

I just upgraded to the latest FF version 147.0.2 64-bit and now the video's on Facebook stop playing when I change to another window. As soon as the FB windows is not selected (in focus) they stop. Going back to the FB window, the video can be restarted.

Can you please investigate/fix this? Thanks!!!

When I try to full screen any streaming site on Firefox I can see the desktop on the edges, the video isn't fully centered on the screen. I have tried updating Firefox, my drivers, restarting my computer and even checking to make sure the resolution and aspect ration were good. Is there maybe an issue or bug I can try and resetting with a setting on the browser?

Browsing this website article I can see that there are embedded Youtube videos in the article but they are not loading, instead I only see blank spaces. I've turned off all extensions, turned off tracking protection, cleared cache and cookies for both the website and Youtube.com, and tried viewing the website in troubleshoot mode.
