A recent set of system updates appears to have made most website videos not play in Firefox.

When I inspect the Developer Tools - > Console tab the most detail Firefox gives are an error line similar to: Media resource URL could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006)

Internet searches for the error name and error hex do not appear yield any applicable troubleshooting, nor any methods of collecting additional problem data.

How can I obtain more detail on where the error is happening and how Firefox might be interacting with other packages present on my system?

Arch Linux has some older ffmpeg-compat packages, but those don't appear to match any of the web results, in that they're even older versions of ffmpeg.

yay -Ss ffmpeg-compat aur/ffmpeg-compat-55 2.3.6-4 (+24 0.00)

   Compatibility package for ffmpeg to provide versions 55 of libavcodec, libavdevice and libavformat, not anymore provided by the ffmpeg package

aur/ffmpeg-compat-54 1.2.12-4 (+87 0.00)

   Compatibility package for ffmpeg to provide versions 54 of libavcodec, libavdevice and libavformat, not anymore provided by the ffmpeg package

For some reason, the bullets used to hide a password are not rendered properly in Firefox. As shown by the first uploaded image, they are displayed as big white-filled circles.

This problem does not occur on chromium-based browsers, as shown by the second uploaded image, which is a screenshot taken from chromium, on the exact same session.

I have already done the following:

• verified that the "Allow pages to choose their own fonts, instead of your selections above" box is checked in my preferences. I have also tried disabling and re-enabling this option
• launched FF in troubleshoot mode to disable extensions and hardware acceleration
• verified that gfx.downloadable_fonts.enabled is set true in my about:config

All of these attempts however failed to solve the problem.

This problem is occurring on a fresh install of a Linux distro, so I first thought that I might be missing some fonts, but the problem might lie somewhere else since the symbols are properly displayed in chromium-based browsers.

A marquee markdown is not showing in every firefox version I tried (Normal, nightly and dev), none of those versions was showing this markdown. So I'm writing about that. I know it's new, but I think it's very good, and useful markdown.

Suddenly my Firefox browser won't open popular websites, such as Schwab, Facebook and Wells Fargo. It displays an error message that the site uses Java, and that I need to enable javascript. When I check in Settings, javascript is already enabled. I tried restarting and reinstalling without success. When I use the Chrome browser the sites work normally.

Hello, about 1-2 weeks ago a very strange problem occurred - on some pages videos don't play at all or play without a sound. Can anyone help me with this strange situation? For example, every video on youtube.com plays without a problem; on facebook.com every video plays with no sound at all; on some other pages video doesn't play at all. This problem is only with firefox, if I try to open the same videos with another browser everything is fine.

I have used a free Hit Counter for many years that I got from https://www.freecounterstat.com/

I have 3 such counters and have stopped working in the latest version of Firefox on my desktop. They work with Firefox on my iPad and Android phone. They also work fine if I use the Edge Browser but I prefer using Firefox as I have for many years.

The embedded code is pretty simple, here it is for one of my counters... <a href="https://www.freecounterstat.com" title="visitor counter"></a> Can you help? Thanks, Bill T

Concurrent with updating to Firefox 126.0, when typing into the address bar, the list of suggested sites covers-up the address bar. In fact, the top of the list is off the screen. I don't see any other posts relative to this, am I the only one with this problem... and how do I fix it?

So i wanted to remove borderline between text bar and tab bar. After some googling i manege to do so by console(contl+shift+alt+i), in string "--tabs-navbar-separator-color: light-dark(rgba(0,0,0,.1), rgba(0,0,0,.3));" i change 3 to 0 and borderline gone. But every time i restart browser is all back. Is there any way to make it permanent ?

I just updated to the latest version of Windows 10, and now when using Firefox (126.0), the url dropdown menu rather than dropping down now "floats" over the browser window with the top cut off. The top url is still there, and I can navigate to it using the arrow keys, but it doesn't show. This is new as of this morning, when Windows updated. No issue in other browsers.

This has been a problem for a while, currently on Firefox 126.0 and Nvidia 550.78. I can work around the problem by forcing webrender to use software mode.

When using HW accelerated webrender with my Nvidia graphics card everything works fine until the PC wakes from sleep, then graphics are broken and Firefox needs restarting. Most noticeable for me is when looking at Grafana graphs they will look like random lines, and my Frigate NVR snapshots only display some of the time.

Is there anywhere in Firefox that will show a log of any error messages to do with the graphics card? I would like to try and fix the problem rather than disabling HW acceleration, but with no logs to look at that is impossible. No other programs seem to have a problem with resuming from sleep, and no error messages are shown in any of the system logs.

The PCH.com website says that I need to remove (whitelist) Adblock from their site in order to be able to play the games on that site. Firefox extension site says that they have removed Adblock....I need help!

Every time I open the Firefox browser and start typing something in the address bar, the address bar removes everything I just typed after a few characters, which makes me type usually half the websites name on accident because of this bug. After the first occasion when launching the browser, the address bar works completely fine again.

Please advise how to prevent extensions, especially 'dark reader, ads blocker, etc. from loading thus forcing me to refresh Firefox desktop browser constantly? Thanks. Petar - drmitov@gmail.com

I'm running Windows 10, Firefox Release 126. I had the same issue with the previous version of Firefox. I was hoping 126, would fix the Chase Bank issue.. But it did not I read several articles from FF users, I checked my User Agent Settings, they are correct. Called Chase, they said use Chrome as Firefox does not have the 'needed code' to work with Firefox. Been using Firefox with Chase for at least 5 years.

Please help, Thank you

Whenever I browse the web using Mozilla (Google, Startpage or any other browser) AND Mozilla is set to fullscreen mode I get black bars all around website screen which are not present when Mozilla is set to windowed mode.

I am using: Macbook Air M1 (MacOS Monterey 12.6.6.) and latest Mozilla web browser. I have already tried this solution: "go to about:config in the address bar and try changing the value of full-screen-api.macos-native-full-screen to true" and it did not fix the issue. I am experiencing this for a lot of time now and only on my Macbook which means a specific version of Mozilla cannot be blamed. This happens on ALL websites. Note: I did change about:config quite a lot regarding privacy alterations.

Once again, Firefox updated itself w/o warning. As a result, the YouTube list of videos I wanted to watch has been lost. The "Restored Session" only contains the current video, not the queue of videos I'd been looking forward to. I had Firefox set NOT to auto-update, but apparently the last Update changed that as well. I was happy with the previous version, and didn't need or want an Update, at least not now. Could you please either fix the Restore Session to include the WHOLE web page, including YouTube queues, or make the Do Not Auto-Update choice persistent through Updates. Better yet, both. (I've just reset the about:preferences>settings>General>FireFox Updates>Allow FireFox to... box to "... let me choose to install them." Let's keep it that way!)

I view a lot of PDFs for electronics design. And after some time with the browser running it starts to garble PDFs. I have not found a trigger. Sometimes it opens fine in a new container tab or private browsing, other times nothing will open it. Very occasionally refreshing a few times makes it load correctly. The error doesn't manifest for all PDFs at the same time. Open ones will remain viewable, and once the error occurs some new PDFs still open while others fail consistently. Sometimes opening the same PDF as a file from my local drive makes it render.

The rendering error is a bit unlike anything I've ever seen. There is a lot of X and Y spearing like it tried to render the same text and images in slightly different spots over and over again. When I switch virtual workspaces and come back some parts of the rendered page retain the contents of the previous workspace and others do not. Scrolling produces jitter and additional smearing.

One somewhat reliable way to trigger the error is to put the laptop to sleep and wake it up. That always causes PDFs to exibit this error but often refreshing the PDF will work to restore it. Not reliably though.

I've attached an image of the error captured with my phone because neither screenshots nor OBS can actually "see" the garbage on screen. Apologies that this error is so full of inconsistent behavior. I've lived with this for some time now in the hopes that it was a temporary problem and tried to work out what causes it but I can't find anything other than putting the laptop to sleep being a cause, and even then it is not the sole cause.

Hello! I am trying to create my own theme using Firefox Color, but the custom image I uploaded doesn't show in the actual theme, only the little preview. It is definitely small enough, so I do not know what the problem is. Is this able to be remedied? I am adding a screenshot so you can best understand what I mean. I have not used FireFox Color before, so if it is an obvious fix, I apologize for the trouble. Thank you, have a great day!
