Firefox Support Forum

I have a very good PC (5800X3D, 7900XT, 32GB DDR4 3600), but Firefox (either the normal, canary and nightly version) can't play smoothly any 4K video (like the Borderlands trailer: https://www.youtube.com/watch?v=lU_NKNZljoQ ). 1440 and lower resolutions are fine, as are 4K videos on Chrome and Edge. FWIW, my CPU during 4K playback is barely used (1-2%), and my GPU's video codec (VCE) is used by around a third. Disabling HW accel makes things better, as it still stutters but it's (barely) passable. I already tried creating a new profile, but still it's the same.

YouTube all of a sudden started to slow down and only be able to load videos fast enough in 360p resolution, I tried watching YouTube on Microsoft edge and YouTube handled 1080p easily there, I have cleared the cash and made sure my Firefox and Windows are up to date and still the issue persists.

this only seams to occur on YouTube as amazon prime and speed test works without issues

I have used Firefox since forever, was a Netscape user in the past

But for about 3 months Firefox simply is no good anymore\

It is more and more sites I can not access with Firefox and have to use Edge instead.

Last example, just now

See screens attached

This is just one example, many other sites simply do not open, or open properly, in Firefox

WHAT IS HAPPENING?

Thank you

Scrolling in Firefox is causing any webpage to scroll many lines at once with a single click, and it seems to be exclusively happening to Firefox, as every other application scrolls normally. I have tried searching here and elsewhere for a solution, and I have tried to change about:config settings based on the recommendations I could find to no avail. I have also tried to refresh Firefox and have used Troubleshoot Mode, but those too have not worked. I have no clue as to what could have caused this, as I have not been messing with any settings prior to this.

I'm asking this question on a different browser because Firefox cant load any websites.

Basically whenever i open a new tab, it opens to a crashed tab. Gah. It cant even load google, or any website for that matter, not even the homepage for Firefox, its just a blank page with nothing on it, whenever i type something into the address bar and press enter it just disappears and does nothing. Browser settings work, but stuff like passwords dont, and i have most of my important passwords on firefox, so i cant log into runescape and stuff.

Can you help?

From today 4 march when I try to record a voice message on chat from facebook appear an error saying an error as occurred. On Chrome it work, from facebook app it work

I even tried other facebook ids and firefox profiles and ever the same. Even disabled the anti popup ublock

In all case I haven't added any conf or adon or other inside firefox, I use same conf as ever and from many years.

Today messages from microphone in chat does not work and facebook say an error occurred Is written in italian but say what I said

Whenever I attempt to watch something on any streaming service, I get an error message from the streaming service and a note from Firefox saying "The WidevineCdm plugin has crashed." I have tried to solve this problem a number of ways, but have unable to find a solution.

My best guess is the problem is due to the most recent WidevineCdm update, as in the plugins settings the most recent update for the plugin was on 10/21/23, which is shortly before I first noticed the problem. I did test out various streaming platforms on other computer browsers (Chrome and Microsoft Edge) — they gave the same website errors as I got on Firefox, but those browsers did not indicate the cause or suggest which plugin failed. I additionally tested out desktop apps for some of the streaming platforms; they work fine without any issues, but unfortunately the main streaming platform I use doesn't have a desktop app and only works in browser.

My computer is a Lenovo Yoga 9i, it's running Windows 11, and everything is up-to-date.

The methods I have tried to fix this issue with, to no avail: - submitted crash reports - toggling the "play DRM restricted content" options in Firefox, and toggling whether or not the WidevineCdm was activated, closing the browser between each toggle of options - clearing Firefox's cache - running Firefox in troubleshooting mode to make sure it wasn't a different extension interfering with it - tried running Firefox in compatibility mode - tried to find support from the people who made WidevineCdm, but apparently they don't do end-user support - deleting the WidevineCdm manually from the program files for Firefox and Chrome (since Firefox says the plugin is from Google), and then reinstalling it via the chrome components page. This briefly lead to the message on the plugin page that WidevinceCdm would "begin installing shortly." It seemed frozen like that for a good while, but then I tried clicking the "check for updates" and that message disappeared, and it went back to crashing when I tried using a streaming service. - uninstalling both Chrome and Firefox, restarting the computer, then reinstalling both browsers

As far as I can tell, the plugin comes automatically installed in the browser, and there isn't an alternate plugin for decrypting DRM-restricted content. If there's a way to set the WidevineCdm to a previous version before the update that's crashing it, I haven't found it, but I am no expert in computers or coding, and my guess about it being caused by the recent update could be wrong too.

I'm at my wit's end here, any help fixing this problem is greatly appreciated.

I recently purchased a new Mac Book Pro. After migrating my data from my old one I noticed that when using Firefox my Facebook account was not working properly. I no longer could access my own page or the pages of friends. However, I could access some group accounts I'm associated with. On Safari, everything works fine. I suspect something must have been compromised during the data migration.

I deleted the Firefox app from my new computer and then reinstalled it but to no avail. When I'm in Facebook and try to access my page I get an error message. My OS system to up to date and apparently my Firefox is up to date as well. Any suggestions? Thanks!

This has been happening for months now, on multiple devices (I have tried at least 3 different devices), and on multiple networks.

I have read the articles in here, but they just want me to check network configuration which is exactly the same for all browsers.

If I restart firefox it starts working again.

How can I prevent it from breaking randomly? This is the only browser having issues, I'm almost positive is some bug and not a configuration thing, given that it happens under multiple circumstances and devices, while Edge and Chrome simply keep working just fine.

There is no consistent repro I can give, afaik it is just random, at some point Firefox just decides to stop working and I have to restart it. This disrupts my work and browsing activities as I can lose progress on input forms and similar actions.

I am running Firefox 121.0.1, which is currently up to date, on a slightly older MacBook, which has the latest MacOS it can get: macOS 11.6.8. As the title states, YouTube is almost unwatchable on my machine. The video will pause frequently while audio continues, motion is not very smooth, which is especially noticeable watching sports, etc. I cleared cookies and cache, I have run in Troubleshoot mode as well as tried flipping some switches in about:config that I've seen in YouTube videos and forum posts about similar issues, but nothing has solved this issue.

YouTube in Google Chrome works fine, and I've been watching HD YouTube on this laptop with it for years without any issues, so I doubt it has anything to do with machine specs like RAM, CPU, etc.

I was hoping to make Firefox my new browser and start supporting browsers that aren't chromium based since Google Chrome is going too far with respect to privacy and the freedom to use the add-ons I like (e.g. adblockers like ublock origin), but so far I have not been enjoying Firefox for YouTube. Any help would be greatly appreciated.

Since a couple days ago I cannot Copy anything in Firefox. Be it with CTRL+C or RightClick>copy. I can paste juste fine, and it works on any other app and browser I own. I tried to restart in safe mode (no add-on) but the issue persists. I ended up resetting firefox and it solved the issue... For a couple hours.. then it came back and I can't copy anymore. I did check that I was using the latest version of Firefox windows. I only have two add-ons, but since in safe mode it still doesn't work I'm not sure it's related to that. I also checked that Firefox was allowed in the firewall (I don't know why that would help but a forum said to check that).

Thank you for your assistance:)

Using the arm64 version of Firefox on a Surface Pro X causes several graphical issues. These issues started either with a update of Firefox or drivers.

This topic has already been reported, please see here for more information and documentation: Reddit: https://www.reddit.com/r/firefox/comments/182iojx/firefox_arm64_graphical_problems_on_surface_pro_x/ Mozilla Connect: https://connect.mozilla.org/t5/discussions/firefox-arm64-graphical-problems-on-surface-pro-x/m-p/52086

What can be done to report this issue and help it getting fixed?

I like to split windows so I can have running YouTube videos on the left half of the screen and browsing the web on the right. If I open another site on the right side of the screen that has multimedia (ESPN, CNN, IMDB), the video freezes on the YouTube window but audio continues to play without issue.

I have done the following troubleshooting steps:

• Hardware acceleration turned off/on
• cleared cookies/cache
• A few About:config fixes

Videos don't have a problem running if I open YouTube with Chrome and continue to use Firefox for surfing.

Hey,

I've been having an odd issue with Firefox where tabs where I attempt to access youtube.com will immediately crash. This issue first arose when I attempted to log in to Youtube, and had never occurred before. When I did that login, the tab crashed, and I have been unable to access the website since (100% crash rate).

Basic details: The website does not visually load at all. However, the URL bar icons for the website do briefly appear prior to tab crash. (Autoplay button, etc). The crash is never reported in about:crashes.

I've tried the following tests, unsuccessfully: - Logging out of all Google accounts separately - Disabling all extensions - Transferring all of my data to a new computer - Reinstalling Firefox - Rebooting Firefox in troubleshooting mode

This problem does not occur on my Windows machine but occurred on my previous intel-based Mac and now on my current Apple Silicon Mac.

The only success I have had is in creating an entirely new Firefox profile. However, I would prefer to fix the issue, as I assume that porting all my settings to the new profile would... also probably bring the bug along.

Thanks for reading & any advice is appreciated.

I frequently open new tabs by right-clicking the current tab and choosing "New Tab" from the context menu. Naturally, I want to start typing a URL or search term.

But the focus/cursor/caret is nowhere and typing does nothing. I have to click on the address bar, and then I can type.

I'm not using New Tab Override and I have Firefox's new tab set to a blank page.

I tried disabling all my add-ons, but I still had the problem.

I tried setting new tab to the Firefox home page and for a short while I got a cursor in the address bar. But the problem returned after a few hours

Any clues on what might be wrong? Firefox version 120.0.1 (64-bit) on MacOS Ventura 13.5.1. Thanks!

(A similar problem is described here: https://support.mozilla.org/en-US/questions/1420220 -- but in my case this is not a container tab.)

Hello, I am running Ubuntu 22.04 (Firefox v 121.0) on a custom PC. Ryzen 5700G, 32GB Ram, 2TB Storage, and a Radeon RX 580 (just to give some insight into the system in case it is useful). I use multiple mozilla services and haven't had many issues up until now. Everytime I open Firefox it immediately it fires right up, the moment I try to open a tab, search, etc.. it begins to lag. It will then freeze the browser and my entire PC soon follows suit. I have had to hard reset the PC about 3 times now. I originally had the snap version installed and thought that installing the deb package would fix the issue. I completely uninstalled the snap version and turned off unattended installations in case the system tried to reinstall the snap. I then installed the deb package and fired it up again, only to have the same issue. I have ruled out a couple of things on my end. I entered Firefox Safe Mode and unchecked all of my extensions (the only ones I run are Ublock, Bitwarden, and Relay). I ran a mem test and have been monitoring Psensor to ensure the CPU wasn't overheating (both of these tests were fine). I also scanned my entire PC to ensure I did not have any viruses (clamscan reported no viruses). I have been running my PC for about an hour now without starting Firefox and using Chrome, and I have had no issues with freezing or anything similar to what happened with Firefox. Not sure where to go from here. I love using Firefox and would love to get back to surfing as soon as possible! Any tips/help would be greatly appreciated! PS I could not find any logs about the session. I looked in ~/.mozilla/firefox/Crash Reports/events and couldn't find anything. If there is another place they are stored let me know and I would be happy to send them. I just don't want to open Firefox until I feel it is safe for my PC.

I forgot to add: I disabled hardware acceleration as well, did not fix the issue.

Firefox is becoming more and more buggy and more unstable using more than 8Gb of ram in either the apps processes or if not there then in the background processes and when you look into the firefox task manager it reports it is using no more than maybe 100 MB of ram the only way to stop it is to close the one process that is using all the memory. when i investigate using the about:memory function it tries to tell me that it is an extension using the memory but if i disable the 2 extensions i use and reload the measure memory it still is using exactly the same amount of memory. is there any sort of fix for this because i am getting sick of having to have the windows task manager open to close the rogue process every time i use my browser

I've had a problem recently with some sites (such as support.apple.com, but also others) loading very slowly or not loading at all.

• Restarting Firefox fixes it for a short while
• I've tried changing to No Proxy from Use System Proxy Settings - this, like restarting, helped for a short while
• Unchecking DNS over HTTPS: DID resolve the problem but I'm curious as to why. I enable it with Safari with no problem.
