There is no audio on any website in Firefox only. I'm using Windows 11

1. Numbered list item When a video is playing there used to be an audio icon showing the tab is playing audio, this does not show anymore.
2. Numbered list item Firefox does not appear in the Windows volume mixer
3. Numbered list item The Firefox Task Manager Utility 'Windows Media Framework Audio Decoder is always idle.
4. Numbered list item I've restarted the Windows AudioSrv service and Windows explorer process

Nothing works. Please help.

I have multiple monitors and most often have Firefox windows open on each. Lately, I've been noticing that the Desktop Window Manager process is consuming a huge amount of RAM. At the same time, consumption completely disappears with the closing of Firefox windows. Video: https://i.imgur.com/pHCa7Hh.mp4 (I left it for a while then closed Firefox windows) After a while, I noticed that already 13 GB of memory is being used by DWM. I don't know if sites affect behavior, but most often I have https://music.yandex.ru/home open

OS: Windows 11 (Microsoft Windows [Version 10.0.22621.1928]). Firefox: 115.0.1 (64-bit) Screen setup: 1 - 3840 x 2560 with 200% scale, 2 - 1920 x 1080 with 100% scale.

Firefox just turns into a black screen and becomes unusable. It has been happening for a long time now and i have checked RAM and CPU usage and they are all fine, as I explored potential causes.

I will be using firefox and it just turns all black on all screens and is completely unusable. To use it again I have to force close all windows and reopen it and it works again.

This is a frequent issue that I have seen

Just updated to the latest firefox version 119, and noticed that the url links are now all underlined again. Checked the support page that says it can be undone in settings, but when I opened up to the said setting page, there's no option to uncheck underline links. Where else can underline links be disabled?

A white screen occurs when browsing the web. If you turn off "Use recommended performance settings" and "Use hardware acceleration when available" the problem is fixed, but then the browser slows down. Can this be fixed in another way?

Firefox 114.0 (64-bit) / Windows 11 Home 21H2

hello! i've been having an issue with mozilla where webp images are not loading at all. this is especially prevalent on youtube, where thumbnails simply do not load, as well as on tumblr, where if an image or gif is a webp file, it will refuse to load. both are attached in the image below to see the difference between firefox and chrome, as the images load fine on chrome. as well as that, discord, when opened with browser instead of the app, does not load profile pictures, server icons, or custom emojis. google hadn't helped me at all, and i don't know what to do at this point. i don't want to go back to using chrome.

in the attached image, the top images show a set of shark sculptures. the first does not load on mozilla, and looking at the image file, it is a webp. the second image is revealed to be a jpg, which mozilla treats normally. in the second set of images, there's a quick look at a random youtuber's page, the top being mozilla and the bottom being chrome, and you can see the mozilla thumbnails do not load.

thank you for reading! i'm very confused and am unsure what to do. any help is appreciated!

I am unable to sign into Costco.com using Firefox. I get an error message:

    "Bad Request - Header Field Too Long
    HTTP Error 400. A request header field is too long."

Turning off all extensions didn't help. Opening a private browsing window DID work. Using Chrome DID work.

Thanks!

When I go to bookmark a web site, as I start to type the bookmark folder name it vanishes.

I have to go into the bookmarks folder, find the no name folder and type in the new folder name. 

As I start typing I have to enter the first letter twice as first strike does not work.

I have thousands of bookmarks which are set up in a Book, Chapter, Paragraph, Sentence format. So when a new folder goes missing it is easy to find the unnamed or a folder with no name. Thank you for the help.

firefox not opening since 2022-01 Cumulative Update for Windows 11 for x64-based Systems (KB5008353). I reloaded Firefox. Google Chrome and Microsoft edge work OK. Task manager shows running but stats never change 0% CPU/0.2MB Memory

Submitting using Chrome, which may have to become my default browser.

Firefox 96.0. Windows 11 Pro Version 10.0.22000 Build 22000

Since installing FF 96, the program has stopped loading pages. Will not even load home page. Starting in troubleshooting mode sometimes works, but sometimes does not.

No extensions are installed.` I have tried Refreshing. I have uninstalled and reinstalled. Neither helps. Multiple instances of FF are started with every launch, even when the launch results in a blank page.

Any advice would be helpful.

Thank you,

So yesterday I got a new computer and downloaded Firefox to be my default browser. It worked fine the first few hours -- I was able to log into my account, set up my extensions, and use the browser as intended. A few hours in, though, it completely crashed on me. I am unable to go to new websites, refresh a page, open bookmarks, log in to my Firefox account, or even open settings; the home screen also doesn't load when I open a new tab. Literally the only thing I can do is freeze the Bookmarks Toolbar and customize the Toolbar. I tried closing and reopening, refreshing/resetting the browser, restarting my computer, going into Troubleshoot mode, deleting and redownloading the application, but nothing is working. I have no trouble with Firefox on my previous computer or my phone, and Edge is working fine on this computer. I don't know what to do anymore. Any help would be much appreciated.

the new update removed all of the websites that were listed in catagories on the left side of the browser window and I don't know how to put them back. They were all the important websites that I go to regularly.

Ever since upgrading to windows 11 firefox developer edition will not work for me at all.

I have reinstalled it multiple times now and every single time its the same thing, after a fresh install I can open the browser, use it once, close the browser and then it breaks and I am unable to use it again - sometimes i cant even open it up again it creates a background process in the task manager but never appears.

• - None of the tabs will load anything at all including any of the settings pages or debug/troubleshooting page (about:<page>) - its like it doesnt even attempt to load anything its completely unresponsive
• - Clicking on any buttons in firefox/options menu do nothing
• - If i close it i see between 2-10 firefox processes appear in my task manager which i have to go through and end each task before i am able to open the browser up again and even then that doesnt always work.
• - Because it opens a bunch of processes when you close the browser and this prevents it from re-opening it is not possible to put it into troubleshooting mode
• - Even after a fresh install (described below) after re-installing the browser it always opens for the first time with a message saying that 'I have reinstalled firefox would i like to refresh the browser' with a button to refresh - If i click this refresh button it instantly breaks it

In order to fix this I have to completely remove firefox from my machine including:

• - Everything in my users folder
• - Everything in program files/programdata
• - Search my C:\ drive and remove all traces of mozilla/firefox i can find
• - Clear all temp files
• - Run a disk cleanup
• - Restart my machine

Before i can attempt to install firefox again. If i dont do this after i reinstall it opens firefox up in exactly the same state it was in before i uninstalled it, same tabs open & completely unresponsive.

I am unable to livestream video services from a monastery in the UK. I have clicked into the little shield at the left end of the web address bar in order to turn off the enhanced protection, but this does not have any effect, even though the website shows up as having had the protection disabled. I don't know whether I need to do anything in Firefox settings.

I was advised to use Google Chrome, and that browser does let me enter, but I prefer to stay with Firefox for all my browsing. I am an elderly person, and have to work harder than my children and grandchildren to keep up-to-date. If you could help me with some very clear instructions with the minumum of technical jargon I would be most grateful. I submit below a screenshot of what I see on the site despite the protection having been switched off on the little shield.

Hi,

Since the yesterday installment of Firefox, the Download list popup every time I download a file. I tried to toggle about:config->browser.download.panel.shown->false but every time I download a file in toggle back to true & the list pop up

It's very annoying. Any suggestion please?

Hello, Can someone please tell me how to stop my "search bar" text from also showing up in my "address bar"? I have search the internet and found all of the following ways that have been suggested that have not worked.

I read that I should set the following to "false" to solve my problem.

1) keyword.enabled 2) browser.fixup.alternate.enabled 3) browser.urlbar.suggest.surches

I have also gone into the settings menu and un-checked everything I could find about suggestions or words or anything else being added to the address bar. The only thing that should show up in and address bar is................you guessed it: AN ADDRESS!  :-) Thanks so much for your help.

I really appreciate the help. Mark
