Firefox Community Forum

I am running Firefox on Linux. Desktop environment is KDE. Compositor is Wayland. I have a 11th Gen Intel Tiger lake Core i3 with integrated Intel UHD Graphics GPU. I do not have a eGPU or any other GPU apart from the integrated Intel UHD Graphics GPU. Intel drivers are installed and are being used. Please see the details given below from about:support for more details. What I have observed that Hardware acceleration, specifically WEBRENDER_COMPOSITOR, WEBRENDER_SHADER_CACHE and WEBRENDER_DCOMP_PRESENT are disabled. The details are given below.

I have enabled the force hardware acceleration too by setting the property media.hardware-video-decoding.force-enabled to true. But still the above three hardware acceleration are still not available.

How can I get these enabled?

on the game 'my little farmies' by upjer, when I go to fullscreen, a blue haze covers the entire area making it difficult to discern colours. I have cleared cookies and reloaded the game, switched the pc off and on again. nothing makes it go away. does anyone have any ideas. i have asked upjers but they say it is a firefox problem. many thanks for any forthcoming suggestions.

How do I resolve this issue

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

I was in C-Panel looking to delete emails as the serve is full but wanted to see the emails before I delete them. The 38000 or so of emails had downloaded and I began the process of selecting and deleting when I got the message that this page is not redirecting properly. was never a problem in the past but is now why?????? and how do I resolve as I cannot received anymore emails until i clerar out the server?

Hi,

I use firefox nightly as my everyday driver for WEB. So far I was very satisfied with the performance and mostly with youtube videos and hardware decoding. I use a Nvidia 1060 (GP106) which supports VP09/AVC1/H265 decoding.

The problem started only recently after some updates of the Firefox when I noticed that VP09 isn't hardware accelerated anymore. They way I test is using the Windows 11 task manager/Performance/GPU/Video decode.

At the same time, the stable Firefox has no issues with VP09 HW decoding. The same is valid for any other browser I tested. So the problem is isolated to the nightly.

I downloaded and ran mozregression GUI which indeed showed me that some nightly version before the VP09 worked just fine. I tested using the dates option of the tool.

This is the push_log URL from my test.

Thanks in advance for your help

I just got a new Epson 3-in-one printer and tried to sign up for the warranty. I got a message that the warranty was expired... I went to the Epson support site on Firefox and Malwarebytes blocked the site as malware... It said I could add the site as approved, but I don't know how to do that. "https://www.epsoncom.com/my-account/home". The Epson site said I already had an account but my password was incorrect. I had an Epson printer more than ten years ago; I don't remember the password and they don't provide an option to reset it. HELP, PLEASE.

Hi there my default browser is Firefox Mozilla but certain sites open very slowly or not open at all. All things I did were clean the cache, reinstalling Mozilla software but nothing works and its a bit frustrating. Also Adblock Plus wont work on you tube. Thank you in advance Kuba

Since the last Firefox update, I am unable to sign into my Outlook account. When I click "Sign In" it opens a new tab with the sign-in buttons. Works fine in Edge and Chrome.

I have a 600 Mbps internet connection with Infinity. It measures the speed on Chrome, through my router, however, Firefox only measures the internet speed at approximately 400Mbps. Firefox is slow. I have done all thing suggested to make Firefox perform better. What has happened to this browser? Also the Browser when loaded with too many tabs freezes and has to be forced quit. I started using Vivaldi that measures over 600Mbps. Comments. My laptop is a older iMac that still works perfectly running High Sierra. No more Mac's, Apple has lost it way on producing computers, and has defaulted itself to a phone company.

Attached is a screen shot that shows Firefox trying to measure the speed, but the test has frozen, will not complete.

I have downloaded Duolingo on my Windows 11 laptop. When I try to run it, it says that it can not open it because it can't find Microsoft Edge. This is the latest version of the app. I can't find anywhere to change the Duolingo default browser. I have Firefox set as MY default browser in windows settings. I also have AVG Secure Browser installed on my laptop but seldom use it. I donot have MS Edge installed on any of my computers. Can anyone help me find a solution to this problem? What other information do you need?

I am sitting in hospital with a weird problem. The connection is open and thus not secure. I have successfully connected my 2 android devices, however my Windows Asus laptop is being barred by firefox. I only run firefox. It is a dead end because firefox refuses to allow me to access the net at all. So now I have to get my wife to go and download chrome and see whether that will work. Why can I not override as u understand the risks I also use Norton 360 with its VPN.

My FF browser freezes, suddenly closes all tabs, expands fonts, etc etc All else in my system is normal. Should I just use the default MS Edge and be done with it?

Hello, using Windows 10 Version 22H2 (Build 19045.5965), Firefox 139.0.4, Thunderbird 139.0.2, I can drag multiple emails from Thunderbird but not drop them into Firefox (the stop symbol appears and does not let me finish the action). However, dragging and dropping single emails does work. Firefox does not understand the imap address but the drop is registered which is all that is relevant to me. Is this a bug/missing feature in Firefox or a problem with Thunderbird and Firefox on Windows? Or is there a way to do it by simply adjusting (preferrably very few) settings? Dragging and dropping multiple emails using Thunderbird and Firefox on Linux Mint works fine. Dragging and dropping multiple emails from the Windows Explorer to Firefox also works fine. In testing, the issue only arose using Thunderbird + Firefox, Chromium-based browsers also worked fine with Thunderbird. If this is the wrong forum to ask such a question because this should rather be in a bug tracker or something similar, please let me know. If this should be on the Thunderbird thread instead of Firefox, also let me know. Thank you for your help.

so, basically, if i walk away from my computer for a few hours and firefox is open, I come back to the original window, plus a window for about every hour that i was away. all the new windows are just sitting on the homepage, but this only happens when a keyboard is connected as far as i can tell.

any keyboard by the way, i have now tried it with 12 different ones.(6 different manufacturers at least)

i have tried to refresh firefox, i even went so far as to do the "reinstall but keep my file" thing for windows 11, uninstalled and reinstalled firefox, deleted all the local files, cookies, etc, signing out of my account on the browser, malwarebytes said i didnt have any problems with my system.

I have even tried to figure out how to reset the http and https default to none in windows 11 to attempt to solve this.

the only thing that works so far is to not have a keyboard connected

any help would be great :)

When I copy a post in X from Firefox into a text file, it loses formatting, but when I copy the same post in X from Edge into the text file, it keeps formatting. Why?

I know, sounds stupid, but it is what it is. It happens rarely, only with Firefox on the secondary display from my laptop, via HDMI. It starts with some random few thin horizontal bars across the window itself, and soon, it turns off my display. It seems the bigger the window is, the more severe the issues. So full screen usually, it shuts it off and keeps it off. Not black screen, no signal style. I manage to get it out by Winkey+arrow. If i then put it back same issue. If i lower the width of it, it manages to stay coherent longer, but still resets the display with a quick black screen on page reload. The lower bounds on a 1920x1080 display resolution was 1515 pixels. At 1515 pixels, it works fine, once this is triggered, it's very repeatable on 60-70% of webpages. If i drag another window on top of Firefox, the monitor comes back up.

Before anyone asks: I have tried turning off hardware acceleration. I have tried putting firefox.exe to run on the integrated video card and on the dedicated 1060 Max Q videocard. I have cleared cache and etc.

This persists on a Windows session, across multiple Firefox restarts. A computer restart technically fixes it but i have no clue what triggers it. Laptop monitor works fine.
