Diễn đàn hỗ trợ Firefox

134.0.x has seemingly brought in a conflict in the system. When I have Firefox open, the mouse becomes jumpy, the keyboard is often interrupted, and if any music is playing on the system, it becomes a buzzing sound. This buzzing is coincident with the keyboard and mouse issues. I have added no new software or hardware to the system, a Windows 10 desktop. This update has forced me to revert to Edge if I have any need to write, use the mouse, play a YouTube video. Thank you.

Hi there! Ever since I believe two days ago, playing videos in the Firefox browser have been giving me issues. Videos often end up looking scrambled/glitchy. It starts off mostly in green but sometimes turns multicolored, and the tab the video is in starts lagging or freezing. At first I thought it was a YouTube issue, but it's happening on other websites as well, even for animated gifs. I tested some videos in Edge, and so far I haven't had any glitchiness there yet.

I currently have Windows 11, and Firefox is up-to-date. I've attached screenshots from three different websites. Happy to provide other info if needed!

There's a problem with video playback on firefox, where after a while/randomly, the thing happens as shown in the image. I've uninstalled intel graphics driver and reinstall, didn't work, I've refreshed firefox, didn't work, I've fully uninstalled firefox and reinstall, didn't work, and when the error occurs the igpu is at 100% usage (and ram/vram usage is not full). The whole firefox app will be laggy but not windows, and upon pausing the video only will firefox be free of lag, and a refresh will solve the issue. However, it will occur again once in a while, doesn't matter the resolution or volume, and not just youtube but all other video players. It does occur more frequently and predictably when the video is paused for some time, or when the computer sleeps for a while, and I think it has something to do with the way firefox handles ram. (just my guess)

The only fix that worked was setting media.wmf.dxva.d3d11.enabled to false, which is undesirable as it increases cpu usage by at least 20% as well as increasing my battery discharge. Other fix includes using other browsers, using my nvidia rtx on firefox, and (not totally sure) setting the resolution lower.

Also, after the error occurs/before the error occurs, firefox doesn't do that blink-in-blink-out animation when going fullscreen on video players (like chrome), which can be fixed by exiting the firefox application completely and restarting it. Refresh doesn't work here.

For a while now, several months anyway, many of the sites I visit work in Chrome but no longer in Firefox. The sign in or login buttons do nothing, petition submit buttons do not work, etc. I can enter information in the required fields, but I the send/submit buttons do not work.

My test page is the log in for a course I have purchased. Here's what I have tried so far:

    Turned off enhanced protection 
    Paused AdBlock
    Ddisabled Privacy Badger
    Whitelisted the site on minerBlock.

Still no joy.

Anyone have any ideas? Thanks, --elizabeth

I've noticed that when video media begins to play, it often suddenly slows down the entire browser's processing ability and cuts to strange visual glitches limited to just the video window, usually green and pink pixelated glitches. This doesn't happen on YouTube, nor does it happen when I use other browsers like Edge. I'm on Windows 11, using the latest Firefox version, with Strict privacy settings and a reliable and simple adblock. Had the same setup on a previous Windows 10 laptop and did not have these issues. It's getting frustrating and is impacting my experience with this browser across multiple websites. I refuse to switch back to sketchy, predatory browsers like Chrome and Edge, so I hope this can be fixed, either on my end or on Mozilla's. Thanks! (Attached a screenshot of the visual glitches.)

When I open a web page with a video in it, the video generally starts to look like the attached screenshot. It usually happens within 30 seconds, and then it will occasionally clear up for 10 seconds, but otherwise, it's just a shifting swirl of green.

Does not happen in other browsers.

I play online bridge sharing the mic between the bridge app and Firefox. It works most of the time but occasionally Firefox ends the sharing for no reason. The settings are not changed.

Having an issue playing purchased movies from YouTube that have played before for a year on a new HP Envy Laptop. Google/YouTube support had me try to play the movies in Chrome (I use Firefox always) and they played. Google wouldn't provide any further assistance. This is laptop has Firefox as the Default Browser. I believe same settings as my previous laptop, also HP.

Firefox is up to date as well. Any ideas?

I listen to music and videos in tabs by pinning them. When doing so, the "Mute tab" icon is nearly half the size of the pinned tab. I've found others that have had this problem years ago (https://support.mozilla.org/en-US/questions/1411474), but the trick they use to fix this no longer seems to work. Does anyone have a way of simply disabling the mute feature? It's honestly more annoying than helpful because I accidentally click that infernal mute button numerous times a day when I simply want to switch back to what's playing. Thanks for any help.

Hello. I often use a frame interpolation application called Lossless scaling (LS) for watching YouTube videos. LS captures frames from a window using APIs like DXGI or WGC and generates interpolated frames between them. When running LS with YouTube videos played in full-screen on other browsers, it correctly detects and operates at the video's native framerate. However, when using Firefox, the application detects a framerate 2 to 3 fps higher than the actual video fps. For instance, a 60 FPS video is detected as 62 FPS, resulting in poor frame pacing and a noticeably choppy playback. It works fine in Chrome or Edge, but I would really like to resolve this issue.

Bonjour, je n'arrive pas à lire les vidéos Netflix et n'arrive pas non plus à comprendre d'où vient réellement le problème ? Tout est Ok dans paramètres ?

In the last couple weeks i've encountered an issue where video footage, but not the audio or the video progress itself, will freeze if I tab out of Firefox and into a game window.

Here's a video showing the issue

Like shown in the video, It only seems to affect Firefox and not other browsers, and it only happens when I switch to a game window, not other tabs. It should also be noted that although the video only shows YouTube footage, this issue affects every player I've tested it on.

I've tried this both with and without extensions enabled, as well as just about every video player related config in the about:config page, and with both hardware acceleration on and off, still with no luck resolving the problem.

If anyone has had a similar issue and managed to fix it, help doing so for myself would be much appreciated.
