Secure Connection Failed Errors on Most Websites

Starting on October 18, I've had problems accessing most websites. I get security errors such as:

Secure Connection Failed Error code: SSL_ERROR_RX_RECORD_TOO_LONG

Secure Connection Failed Error code: PR_END_OF_FILE_ERROR

This problem occurs only with Firefox. It doesn't happen with Chrome (which I had to use to post here).

A few sites work, but not many.

I tried reinstalling the latest version of Firefox but that didn't make any difference.

Suggestions? Thanks in advance.

We have systems on our network that run Mozilla Firefox when accessing a specific URL are able to do so with no issues. Then we have other systems in our network that run Mozilla Firefox when accessing that same URL received the following error:


Secure Connection Failed

An error occurred during a connection to "URL". PR_END_OF_FILE_ERROR

Both are running the same version of Firefox. The only difference I have found is the DNS over HTTPS status. On the one that the user is able to access the URL, the DNS over HTTPS status is off. On the one that the user is unable to access the same URL, the DNS over HTTPS status is Active using the provider Cloudflare.

These are both brand new install of Firefox and there was no configuration changes. We don't use any GPO's or anything else to manage Firefox. Why would one be off and the other active? This is causing issues.

Firefox on LinuxMint Desktop cannot access pages that I have accessed before

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).

Why am I being blocked from websites? I keep receiving messages 504 Gateway Time-out. The question I searched in google was, what size comb do I use to clip my dog's long hair? It's a simple question. Why did it send me this message 504 Gateway Time-out. I am not all that computer literate so I could use some help please. FYI I used Firefox as my browser.

Thanks.
