Firefox Community Forum

I have recently installed Windows 10 IoT Enterprise LTSC 21H2 build 19044.5737 I am getting following error while surfing some web sites using Firefox latest version. There is no problem with MS Edge.

Looks like there’s a problem with this site

https://linkos.store/qSL9d4V7uDUy2Z9s/1/953 might have a temporary problem or it could have moved.

Error code: 520

   The site could be temporarily unavailable or too busy. Try again in a few moments.

Thanks in advance

Hi

When I browse to https://earthobservatory.nasa.gov/images/154162/clouds-hover-over-the-alaska-peninsula, I can play the shown video once.

When the video is about to start the 2nd time though, the log from the web developer tool says (see screenshot): ``` Media resource https://eoimages.gsfc.nasa.gov/images/imagerecords/154000/154162/ak_cloudwave_vir_20250407_anim.mp4 could not be decoded. clouds-hover-over-the-alaska-peninsula All candidate resources failed to load. Media load paused. clouds-hover-over-the-alaska-peninsula Media resource https://eoimages.gsfc.nasa.gov/images/imagerecords/154000/154162/ak_cloudwave_vir_20250407_anim.mp4 could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) Details: virtual RefPtr<MediaDataDecoder::DecodePromise> mozilla::GMPVideoDecoder::Decode(MediaRawData *): mGMP not initialized ``` and the video shows the warning "No video with supported format and MIME type found.", although the video was successfully played the 1st time.

Note that the first four warnings in the screenshot already appear when loading the page, i.e. before playing the video the 1st time.

The same happens when all installed firefox plugins are disabled.

I am using firefox 137.0.1 (64 bit) on arch linux.

Thanks for help, Chris

When I try to log into ssa.gov I get a Bad Request error. Every time, no matter how I access the website. Only have and use FireFox on my Windows 8.1 desktop computer with Malwarebytes. No problems with other sites. I've read what seemed relevant to my question on this forum, but nothing seems to fit. Thanks, Bernadine

Hi there, I am trying to go to a site that I go often, but getting this message back - "502 Bad Gateway openresty". That happens once in a while, I can generally access the site without problems,. What should I do? thanks

Problem:

       Firefox 137.0.1 on Ubuntu 24.04 fails to load vencord.dev with PR_END_OF_FILE_ERROR

       Other browsers (Chrome, curl) work fine

       Same error in Safe Mode

   What I checked:

       SSL cert is valid (openssl shows no issues)

       Reinstalled Firefox completely

       Reset profile, updated CA certs

       No extensions installed

   Technical details:

       TLS_AES_256_GCM_SHA384 cipher

       ECDSA-SHA256 signature

       Verification shows OK (code 0)

   Need help with:

       How to debug this specific TLS termination

       Where to find relevant Firefox logs

       Known issues with Firefox 137 and ECDSA

   Can provide:

       Full openssl output

       Firefox debug logs

       Packet captures if needed

   Quick test:
   curl works:
   curl -v https://vencord.dev
   Firefox fails even in headless:
   firefox --headless https://vencord.dev

   Tried forcing TLS 1.2:
   NSS_SECURITY_ARGS="version=tls1.2" firefox https://vencord.dev
   Same error

I was trying to go to ssa.gov, today, and hit the button to login. When I did that, I got a 400 page saying: Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I have done this before, and it worked. To test if it was a problem with the web page or the browser, I did it from another browser (Brave), and it loaded fine. Is Firefox sending a bad request? Is this something you can fix.

I am using Mozilla Firefox for Linux Mint 137.0.1 (64 bit).

Launching the new Firefox v137.00, it stalls for a long time, then I get the 'The connection has timed out' error. When I look into the Settings I notice in the Startup that both options available are greyed out. Under that that notice 'Firefox is currently your default browser' is displayed normally. So far I have done the following; re-installed v137.00, restarted with my antivirus & VPN (BitDefender)both on & off with no success. It thens drops an error file crash report but I have no idea what all that code means. Any ideas out there? Thanx In Advance!
