Firefox Community Forum

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).

Hello. Firefox has disabled my Bitwarden, which has all my passwords etc. I really need my bitwarden to work. Can anyone assist me to get the add-on working again? I would really appreciate it. Please see attached graphics. Regards Lana

'Hi,

I keep getting: 'Secure Connection Failed An error occurred during a connection to bstsrs.in. SSL received a record that exceeded the maximum permissible length. Error code: SSL_ERROR_RX_RECORD_TOO_LONG

On sites I have visited for years. It says to contact website owner, but I can't get on the website.

Any advice on what I can do?

I have never had a problem opening my email client before in Firefox, but now after the last time I started my computer I get this message when I try to open my email client (Shaw Webmail):

400 Bad Request Request Header Or Cookie Too Large nginx/1.24.0

Oddly though, it will open if I go into the Incognito window. Why is this happening and how can I fix it so I don't have to constantly into Incognito mode to access it?

Secure Connection Failed An error occurred during a connection to (Firefox and ALL sites) PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR Help advises 'Failed to check for updates' Problem arose on upgrade to Firefox 138 Tried restart, computer reboot and reinstallation

I am not sufficiently computer literate to understand supposed help and support documents within 'Mozilla Support'

It looks like the end of 20 years of using Firefox ... Google Chrome used to submit this request

Why am I getting this message: with no way around it?

I am a designer of Systems for Sustainability and Renewable Energy. I am receiving the message "HTML5:Video file not found" when trying to watch videos online which is stopping me from viewing a lot of new video content.

Can I / How do I resolve this situation?

Hello! I started encountering this problem as I updated my OS to windows 11. I had eset nod antivirus, but uninstalling it nothing changed. Tried to change MTU cache size through CMD. Changed different DNSes Tried to disable all protection settings in browser and in windows settings. Deleted all extensions. NOTHING helped except clearing cache of the browser, but this is fixing problem only before first browser restart. Other browser on laptop works normally without any issues.

The other day I discovered all my extensions have been disabled. I have an old Mac and am not able to upgrade to a newer version of Firefox. Is Mozilla going to offer a solution for people like me who find their preferred browser to now be frustrating and inefficient? I would love to restore my add-ons. Thank you.

Dear Sir or Madam: I seem to have a compatibility problem with my firefox browser. Not always, but often, I get a 502 error when I try to log in to my bank account. After contacting my bank, I found out that their program is not compatible with firefox and that I should use Google, which choose to avoid. Is there a patch or fix that can get rid of the 502 error and allow me to continue using Firefox, which I have used for almost twenty years. I don't want to switch to Google, EVER! Please let me know what options I might Have.

Respectivly, Louis Osip
