Possibly there was an auto update of MOZILLA FIREFOX on our DELL LAPTOP (Windows 11). Now, we cannot get a Mozilla window to open - due to error message:

XUL Runner Error: Platform version '118.0.1' is not compatible with minVersion >= 118.0 maxVersion <=118.0

Can someone please help us get back to a previous version of Mozilla Fire. Perhaps it is a Windows error. I have no way of knowing. Please help me. My email is: [removed email from public] Thank you.

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.

Firefox just updated to version 120.0 I hadn't used youtube for a while. When I tried to play youtube videos none of them will play, only get a green screen with audio In troubleshooting mode they will play Refreshing firefox does not fix the problem

Amazon Prime Videos will not play on Fire Fox. The message says to update Firefox, but my browser is up to date as of today, 10-24-23. Their customer service can provide no answer. This has been an ongoing problem for several months. I have tried their trouble shooting steps of restarting my system, signing out and re-signing in on Amazon and closing and re-opening Firefox. Allow DRM content is checked on my settings. Thanks.

I can sign into YouTube ok, and the pictures of the video's are ok, but whatever I try to watch I get a green screen and just the video sound? It started happening yesterday. I am getting fed up with YouTube and the issues it has with Firefox. I'm having to use Microsoft Edge to watch videos. I've done the 3 resets it says on the support page, but still have the issue. Many thanks for getting back to me.

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.

I can no longer view YouTube videos in Firefox browser because they think I have some kind of add blocker installed. I have never installed such a thing and have no idea how to fix what they are demanding I must fix in order to continue with YouTube in the FireFox browser. In the mean time I have to use some other unfamiliar browser just for YouTube. It appears that some kind of incompatibility has evolved in the recent two or three weeks between Firefox and YouTube.

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

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!

I access a CCTV Network Video Recorder on the same private/LAN that I'm on using an PC via HTTPS. It's been working fine for nearly a year. Recently it won't access via HTTPS any more with the Error Message "Secure Connection Failed An error occurred during a connection to 192.168.1.30. Certificate key usage inadequate for attempted operation. Error code: SEC_ERROR_INADEQUATE_KEY_USAGE

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the web site owners to inform them of this problem."

I've contacted the vendor but they seem at a bit of a loss. I can connect using HTTP, and an Android App (spit) still works too. I did find a Stack Overflow article from 2020 mentioning a possible corrupt cert9.db and/or cert_override.txt files, but as it's so old I wanted to ask for further advice before I start hacking things around. On another PC using the same browser version on the same network I get the attached response, not the same as the one I get and it will allow me to accept the risk. Can anyone help please?

Playing media volume is low. In-page volume is maxed (eg. YouTube video controls). OS Master volume is maxed.

But the volume of the Firefox in Windows Volume Mixer is a fragment of the volume set. If I adjust it to max, it jumps to a fragment of it. If I adjust it to lower, it gets even lower, like a percentage of what I actually set. The level I actually set gets a grayed out slider button, and the actual slider button slides to this lower level. See the screenshot in the attachment.

It may sound like an OS issue, but as I understand, this is the output level set by the application (Firefox, in this case). Rebooting the OS doesn't help.

So I have a video playing on firefox, but the moment it drops from the foreground, it immediately pauses the video (the actual video playback). The audio continues, but the video stops until it is back in the foreground, at which point the video continues where it ought to. I have tried disabling the unload tabs in the config menu as well as disable the foreground pausing or whatever its called, as recommended by previous posts. I used to not have this issue at all, so I'm not sure what changed. Please help! Thank you.

I ran a loghttps://pastebin.com/jydVHHs0 of playing a youtube video mediaencoder? not sure if encoding issue or something else

The videos take a long time to play. I upgraded my system recently and was removing and reinstalling audio-related utilities with DNF.

Intermittently (maybe 1/20 times?), when I try to do a Google search from the URL bar I'll get a tab that doesn't load for about 30 seconds. If I search for the exact same thing in another tab it will load instantly, and if I select the url and press enter it will also load instantly. I am seeing this issue both when entering a search and when selecting text and clicking "Search Google for X".

I found a recommendation on a similar issue to set security.tls.enable_0rtt_data = false in about:config but I have seen no change with that setting.

Hi everyone, When i go to the website config.office.com in firefox there is just a white screen. Nothing more. Instantly white. I have checked if this is an issue at the side of Microsoft but it doesn't look like it is. The website does load correctly in Microsoft Edge.

I tried the following in Firefox: - Firefox is up to date (Version 115.0.2 64 Bits) , I have had this issue in other versions of Firefox too. It's not a new issue in this newest version. - Tried disabling all the security features in Firefox, disabling all add-ons, and disabling the extra security for cookies - Starting firefox in safe mode (Shift click on firefox, then open the website) - Checked the Network inspector. All packets have status 200 (See the first screenshot)

You can check the second screenshot for the white page.

Some help is appreciated :) Thanks!

Ever since the latest FF update each time I start/re-start FF I need to resignin to Dashlane. Honestly this hasn't happened in over 20 years. I haven't been able to find any similar reports. Has and/or can anyone explain why and hopefully provide an answer/work around? Thanks anyone/everyone.

I download a file. It stops and speaks of a security risk. The website is https, but the file is http. Is there a location I can pre-approve all files from the url to override the objection? Thanks.
