Firefox Community Forum

Up until maybe mid last year, I had an RX580 8gb. I was able to game on my main screen and watch videos on my second screen with no issues. Then I upgraded to a 2080 and now a 3070. When I switched to the 2080 I ran DDU. But ever since switching to NVIDIA whenever I game and watch videos, mainly twitch, the framerate on my game and twitch tanks. Sometimes it even causes a timeout or causes the video to corrupt, then I have to close and reopen the tab. From what I can see in Task Manager, the video decode just starts dying. Sometimes if I pause my game and then pause the video the frame rates will return to normal. If I'm watching something on YouTube, I'll instead get audio issues where the sound on the video will lower if the sound on the game gets louder. I've tried reinstalling Firefox, but that didn't help. I've tried messing around with my internet settings, resetting my modem, that hasn't helped either. Drivers are all up to date. My specs are:

- Gigabyte 3070 oc 8 GB - 16 gb ram - ryzen 3600 - X570 Steel Legend (non-wifi) - Windows 11 pro

Am trying to access a TV site and the site appears as a page but does not provide any functionality for days now. Have contacted the site and followed their advice without any results. Could this possibly be a Mozilla issue?

The site address is https://www.ertflix.gr/#/show/Home%20Guest

Thank you

Whenever i try to open YT Videos or other in-browser videos in Full-Screen, the video only fills the screen to like 95%. The top and the left have a small bar, which just shows my desktop background. (See att.)

Closing the Full screen window and resizing the firefox window, repairs the issue. But after a restart it happens again.

Enabling hardware acc. kinda fixes it, but not consistently. And i would prefer to not use hardware acc.

A reinstall did not help and i dont seem to be the only one with this issue.

There is an issue with MKV video playback with MP3 audio track in FireFox. The problem is that MKV video plays MP3 audio track without any sound. With AAC audio track the problem is that MKV video initially downloads whole video and only then plays it. In comparison with MP3 and AAC the benefit of MP3 is much better quality and it starts playing without downloading whole video like MP4.

It would be nice if you add support MKV video with MP3 audio playback.

I am use a Phomemo Thermal Label Printer for labels and packing slips. The print preview shows the whole page, but prints only a partial page and small print. Tried all setting but no difference.. See photos

I see a youtube video ready to play when I open my wifi icon on the taskbar. Only happens when Firefox has Youtube open in a tab and I've watched at least one video in preview mode or on the video page. I really wish to turn it off if I can.

Starting at 148 if a user is using Firefox and attempts to log into our MS RDP Application server using HTML, they can log in, but when they select an application, they get stuck at the loading screen with no progression. If they download the RDP file direct it works fine. It's only when using the HTML RDP website with Firefox.

Things we've tried

• We verified it began with 148.0.
• We've tested on multiple devices across multiple networks with multiple users.
• We've tried fresh installs and we've tried without any add-ons.
• We do have Duo securing that server, but I tested a user under bypass and it went right through.
• All other browsers work fine.

My son tried to voicemail me on Messenger but it said this browser does not support voicecalling. I have used this in the past, still on Firefox. I used to get note that a call was coming ans option to connect or discard. Now there is no option to connect. What can I do to get this service back?

This has started a few days ago. I'm running Firefox Desktop on Windows 11. Browsing is perfectly normal, until I try to watch a video in full screen mode. It plays normally for a few seconds and then my whole system freezes, with no response to any action except for hard reset. This has never happened to me before, and all other browsers I try do not demonstrate the same problem. Is there any solution other than changing browser permanently?

I am encountering more and more websites with problems they attribute to Firefox. Many of them recommend using Chrome or Edge and some insist upon it or they will no longer support problems. Direct TV will no longer work with Firefox at all and they will not fix it. Several of my other regular websites will work partially, but have pages that simply will not work with Firefox. I have resisted using Chrome or Edge for years but it is getting harder and harder to do as on line systems continue to have problems with Firefox and their only suggestion is to use Chrome (which works when Firefox doesn't). Any ideas/suggestions?

When I play a video in fullscreen and type something, when I typed something in the IME and will press Esc to quit the IME, the whole fullscreen will be quitted. The expected behavior is to quit the IME only, and the fullscreen should be quitted only when there is no IMEs.

The issue has been existing for years.

I am attempting to access a website https://my.calbrightcollege.edu/ however when i attempt to sign in i get kicked out with the message below.

Something doesn't look right!

Refresh the page to reload the student portal.

Or contact support at 1-833-956-0225 or email us at success@calbright.org.

I reached out and was advised could be something wrong with the software however I believe I have the latest software as i just downloaded the browser today. I am also able to access the same site on my phone and my IPAD not sure why it wont work here.

When watching a video on a platform and the video needs to load, instead of pausing to load then play it once again, it doesn't stop, making the video audio sound so glitchy that you can't understand it

surprisingly, it works as expected on youtube

This is the message I receive. There is no way a novice could follow these - that's why I am writing.

It happens on all my sights, ie: Facebook, etc.

Tonight Firefox updated itself and when the routine finished the new default-release profile did not contain any of my data including bookmarks.

I tried to launch the profile default in a new browser but this was empty too.

can anyone help me locate my data and restore it in the new profile?
