Windows 10 Enterprise IoT LTSC 2021 In Firefox version 185.0.1 (64-bit), when watching YouTube videos in full-screen mode, the progress bar remains visible at the bottom, while the other icons disappear. Please fix this bug as soon as possible.

Any time i try to watch a video on any website whether that's YouTube or any other social media this happens. Attached is a recording I made and put on YouTube to show you what I mean.

YouTube videos on Nightly are flickering with green and the frames of the video. I am on Firefox Nightly, so it's really just me not sure how to report this bug.. Thanks!

With the new update to the browser the vids for youtube keep flashing green and other websites have problems with videos to, i thought it might be a graphics issue here on my main pc but when i went on to my xbox ally x pc handheld youtube was working fine and as soon as i downloaded the latest firefox nightly update youtube had the same issue as my main pc

Hello All,

I have a somewhat confusing issue that I've only found two posts on Reddit mentioning previously, but there were no responses.

A short summary: On Discord's website, in an audio call, audio will progressively move from stereo/both ears to mono/only the right ear after anywhere from five to sixty seconds. This only occurs on Firefox, it does not occur on Chrome or Edge (with the same extensions, when applicable.) For the record - this also only occurs with the one headset. I've tried with a second headset and don't have the same issue, but I don't believe the Headset is solely to blame since the issue only happens on Firefox.

I have also tested on Firefox Nightly as a fresh install - no extensions, no settings changed, just install and login to Discord.

Specs:

ASUS TUF Dash F15 FX517ZR HP USB-C G5 Essential Dock (Monitors are connected through it) Windows 11 (August update/build 26200.9168) Razer Blackshark V2 Pro RZ04-0453 headset (Connects via USB-A Dongle plugged in to the laptop) Firefox (x64) (154.0.1)

Troubleshooting steps I've taken:

Removing the Audio driver for my computer and re-installing it. Removing/re-installing the drivers for the Headset. Verified all audio related drivers for my device are up to date. Verified the BIOS is up to date (it's solved unusual problems before) Toggling the "media.latency_preference" toggle in about:config (recommendation from a friend) Disabling all extensions on Discord. Disabling Firefox's strict mode on Discord. Verifying all audio related drivers for my device are up to date. Tested on a Firefox Nightly install (the first time it's been installed on my device). A separate browser (Chrome/Edge - the issue is not present) A separate headset (Issue is not present) Downloading Razer Synapse and disabling any "extra" features, and testing with various options on/off. Disabling any and all other Audio devices (speakers and microphones) while using the headset. Charging the Headset to full.

Things I haven't tested, but thought of:

Resetting Firefox in any capacity - I can, but hopefully testing with Nightly is sufficient. A different computer entirely - on my list, when I can next. A new User profile. Testing with no headset at all, and just utilizing the built-in speakers/microphone for the laptop.

Oddities:

Changing audio settings in Windows will "fix" the issue momentarily - for instance the "Spatial sound" option. Changing from one setting to "Off" (or vice versa) fixes the issue for the same ~5-60 seconds until it slowly goes back to the right ear. These options are present for every device, even ones not experiencing this issue.

It's very odd to me because on one hand it may be the headset, but then the issue is only present in Firefox.

Any help or things to test would be greatly appreciated!

Thank you.

Hi.I have no sound in browsing allthough i have in all other cases.i returned with this problem one more time.I solved it for a while with unmute with videos.But now allthough i have unmute done i have no sound again.Thank you

So i can not open up a youtube video i click on the thumbnail and nothing happens. Ive been working with chatgpt with this promblem and it still hasnt worked. I have factory rested my whole destop didnt help. it works in troubleshoot mode but not in the main one i had the problem on google chrome and i switched to firefox nothing changed and am frustrated I need help talking with chatgpt for 3 hours didnt work.

Here is a video which would demonstrate it best: https://youtu.be/MpHX4Ep-IMM

These two comparison are made between Firefox 158.0 (64 bit) in Troubleshoot Mode and Brave 1.97.59 (64 bit), on Windows 10, version 22H2. I use the 30MB Big Buck Bunny version on test-videos.co.uk site, Firefox seems able to load the 1MB, or 2MB version pretty smoothly, but higher than that, it starts to stutter, for some reasons I cannot understand.

(Most results I can find online tell me to "disable hardware acceleration", but I have been turning that setting on and off multiple times without seeing any changes)

Ironically, videos on Youtube can load normally without issues. It just seems any embedded videos would behave oddly like this, which I encounter most often on Discord.

Please, I would appreciate any insights. I can provide additional information if needed. Thanks in advance.

Hi, I’m having trouble playing Prime Video in Firefox on my 2023 MacBook Pro. The video freezes, or I get a “Video unavailable” message. It happens both on primevideo.com and when I open Prime Video from Amazon’s website.

Prime Video plays normally in Safari on the same Mac. In Firefox, I’ve tried restarting my Mac and router, turning off my VPN, testing in a Private Window and Troubleshoot Mode, and updating Firefox. “Play DRM-controlled content” is enabled, and Widevine Content Decryption Module is listed and enabled. I also found that media.eme.enabled was set to false and changed it to true, but the problem remains.

Could you help me determine why Prime Video won’t play in Firefox and what I should try next?

Firefox version: Version 158.0 (64-bit) macOS version: Sequoia 15.8.1

Thanks so much.

My Firefox auto updated to version 158.0 the other morning and since then, the Twitch video player fails to work. I'll try to watch a stream, but the video player will stay black with a constant "buffering" icon. There was no issue the night prior, before my browser updated.

I've tried watching Twitch on another browser and had no issues.

No videos play. I created a brand new fresh profile, but that didn't help. It seems like maybe there was a recent update, because they worked before.

On tubi it says the widevine crashed and I submitted a crash report for it.

I can't to play the free videos of the moon like this one: https://commons.wikimedia.org/wiki/File:0491_Moon_Travel_01_30_24_00.webm

I am unable to uninstall firefox from the computer because I don't have permissions to do that.

I was hoping someone would have a simple suggestion that could fix it.

I am using the Firefox browser to watch movies that I would like to project wirelessly to my LG Web OS TV. I do not see any tool in settings or your browser's menu that allows me to do this. Google browsers do allow this as well as Edge and Bing. Is there a way to do this on Firefox.

Not limited to youtube

All videos on any site will load properly however they will not play. Can skip around and see frame by frame but the video will not play
