Firefox Support Forum

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

When pausing/starting or moving video feedback volume changes to an fixed volume. Opening video player in youtube default volume is at 41%, I put in at 100% but when I pause it or change to another part of the video, the volume changes to the default again. It's not from OS because with chromium browsers doesn't happen (brave,steam chromium) and with librewolf happens. Wanted to publish a 10 sec video showing the error, because I don't know how to show it with photos.

Hello!

I recently decided to switch to Firefox Developer for personal choices and upon looking at certain sites that use custom fonts, a few of them break and show the default font (Times New Roman) in their places instead. I've tried many solutions to fix this such as adjusting the settings, downloading TrueType fonts, and even messing with the settings in about:config and still the text would not show up properly. For some strange reason, though, the font's themselves seem to be working on the regular version of Firefox but not the developers' edition. I will post examples of my problem below if that helps.

Thank you!

I have to configure a lot of networking equipment! One day I might be working on a brand new piece of equipment and the next day trying to log into some ancient piece of equipment because I need to change something and I can't replace it yet. I'm having a major issue with the redirect even if I explicitly type HTTP it forces it to HTTPS ( and no I don't have HTTPS everywhere installed I've actually never used it ). I've noticed recently a few updates back now that if the connection cannot succeed it redirects to HTTP but it can hang up in a weird limbo where it thinks the site doesn't exist. There needs to be a toggle for local addresses explicitly typed "HTTP" to try that first. There also needs a toggle to ignore the security issues when accessing the device with a self assigned certificate as every single networking device has a self assigned a certificate and every time I need to change the setting on a router I have to agree even though I have a greed for the last 10 times when I've access the device or I just reset the device and the self signed certificate changed. And I don't know how you're gonna handle this on mobile but it almost makes using a mobile browser useless because I might as well just get the computer out even if all I have to do is change a password, SSID or just check a setting.

So local addresses need an option to lower the warning level for self signed certificates and to obey the typed protocol!

And there's some sort of bug with the Logic that detects a certificate or non-secure site that breaks when the connection drops. The only way I've been able to get around this is to go to the address bar and hit enter as a reload will not work and a reload skipping cash will not work to bring the site back up.

I've had devices that I thought weren't working only to find out they were working fine after 3 or 4 attempts and restarts only to find it's just that firefox thought the site didn't exist anymore.

And I don't have any other options because chrome is even worse with HTTPS once it gets it's vampire fangs in you're stuck it will not let you go back. And safari you might as will be undead.

Finally getting annoyed enough to write some thing as every time you go change your setting reboot device check setting log back in change saying restart log back in and you have to hit except certificate every single time.

And while I'm here Bring back the checkbox to save/ not save the certificate as I might not want to save the certificate when I know I'm going to reset the device and it's going to be totally different in the next 10 minutes. Or I might not want to save it at all like I go to a website that's misconfigured and the certificates not valid for the domain name that it's using.

Hello, Mozilla Community Hope you doing well, I'm contacting you to ask for help with a Mozilla Firefox problem I'm having with trying to visit the following website: Geometry Spot Games: https://geometryspot.com/ It won't load, and I'm not sure if that's because of a bug in the website, a browser issue, or something else entirely.

Does anyone else have knowledge of this problem or recommendations for a fix? I've attempted removing addons and cleaning the cache in my browser, but the issue still exists.

I would be grateful for any advice or ideas on improving the usability of the website. Thank you in advance for your assistance.

I'm experiencing an issue, when I visit this website in Firefox, some images appear broken, but they display perfectly in other browsers. Has anyone else encountered this problem or have any suggestions on how to fix it?

So within the past couple of days my twitter/x display setting suddenly switched to "Lights out" from "Default". I can reset it in t/x settings but if I close my browser it resets back to "Lights out" on reopen.

However, this same change happened with other browsers chrome and brave, but if I reset it on t/x it remains changed for those browsers if I close them and reopen.

When I say close I do not mean just that window/tab. I mean close the browser completely and restart it.

What do I need to do to get FF to retain this t/x setting?
