Forum zgromaźeństwa Firefox

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

I need help with a problem that has tortured me for weeks. I use debian 13 with plasmakde. I don't know why, but when I connect to a wifi after some time it doesn't work anymore ONLY with Firefox. I can perfectly use any other app which requires internet but firefox. Sometimes it gives me the error "The connection has timed out", sometimes the error "Unable to find the proxy server" (even if I selected no proxy in the network settings). I searched online but I couldn't find anything helpful, so I can only hope to find a solution in here. Thank you very much in advance!

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.

1. There used to be a choice in settings for Firefix mouse control to be optional. It is no longer available and apparently FF has created default mouse behavior.

The mouse behavior has become errant in a variety of ways. It interferes with everything online and started doing the same on the desktop.

The wheel is configured for three lines at a time on desktop. I do not want the mouse wheel to be doing anything else. I want either or both mouse buttons to open menus and function normally with links, copy and paste.

When looking in about:config the extensive number of configured mouse defaults is shocking. it is impossible to determine how to disable or delete any of them.

It has become impossible to scroll with the wheel and the scrollbar because the mouse jumps all over the page as if possessed.

It is impossible to scroll 3 lines at a time with the wheel, instead the mouse goes up and down and jumps to the top. Changing the number of scrolling lines on Desktop and in about: config so they are both 3 did not solve the problem. Tried changing both to 5 . . . no joy.

Expandable menus no longer open on some websites.

It has also become impossible to us the scrollbar effectively, instead the same behavior manifests as it does with the wheel - the mouse is jerky, going up and down and jumping to the top of the page, unpredictably.

Either way the mouse gets stuck moving up and down. After having successfully scrolled past where it was previously it returns, repeatedly, to the same previous lines each time I try to scroll further - in an endless loop.

If the mouse does functional, briefly, then half way down the page it starts misbehaving again. I already replaced the mouse several months back when the problem started, however, it was not constant. Then it started again with the new (usb) mouse. (Yes, I've cleaned it. No it is not worn out yet.)

2. Via a search I did find a list of adjustments to make in about:config while learning unexpected mouse behavior had become a common problem. I made at least 20 adjustments, and amazingly, there was no longer a problem! Smooth scrolling, no problems. However, after using the browser, closing and opening it numerous times, the errant behavior returned.

3. If there is no way to completely turn off FF mouse control, or use about:config to disable it entirely, then what is the last FF version that allowed saying "no" to what used to be optional mouse control, so it is possible to change back to it? If there is no other way to solve the problem, that should do it.

Any suggestions or solutions appreciated.

16 GB memory, 500 GB SSD. (chose to not install Windows 11 version 23 onward - so in the 22 gray zone that is both a windows 10 install and a windows 11 install - this is the windows 11 install).

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.

I need to install PKCS#11 modul on iMac (OS: Ventura 13.7.4) for signature authorization. I try: Settings-> Privacy and Security-> Certificates-> Security devices-> Load-> Modul filename: /Applications/CertiliaMiddleware.app/Contents/pkcs11/libCertiliaPkcs11.dylib , but I get an answer: "Unable to add modul". In order to install a certificate for signing with a card, I was informed that I need to install this modul first, but it doesn't work. What should I do? Thanks, Martina

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?

Firefox has "Open previous windows and tabs" ticked in Settings. I had to force restart MacOS, and upon starting Firefox again my existing windows are invisible. They are shown in the Window menu and when right-clicking the Firefox icon in the MacOS dock, however when I select one of the windows it does not become visible. Command+` does not show the windows either.

I can however open new windows.

I tried renaming xulstore.json per this old article with no effect.

How can I make the existing windows visible again?

When I play YouTube videos in Firefox, they are constantly choppy and slow, even though my internet connection is fine and other browsers (like Chrome) work smoothly. This happens with both HD and lower quality videos. I've already tried clearing cache and disabling extensions, but the issue persists. Please help me fix this.

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?
