I keep getting pr_connection_reset_error messages in Firefox version 148.0 64 bit. I have purchased the windows 10 OS with extended updates and am running version 22H2 os build 19045.6937 do you have any suggestions on fixing this problem? When I am in my gmail account and using Firefox and I need to do a password reset that is when I receive the above error message.

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.

why do I get this error page when I click on an e mail from Homedepo.com and it I type homedepot.com I get in with no problems. I tried to wipe out the cookies and I wiped out everything that made life easier and made even the easy things like signing in (or really I never had to re sign into my e mail) to my hotmail or gmail? I don't have this problem on my Linux laptop?

My banks account pay bills page will not let me enter. Everything else works as it should. I can get to it on my phone. I use this feature on my desktop this problem comes up.

When using the built-in Firefox AI sidebar and clicking the "Summarize page" button, I consistently get the error: "431 Request Header Fields Too Large" from chatgpt.com.

Cookies were cleared multiple times Extensions (including AdGuard) were disabled The issue persists

Previously, changing a privacy setting temporarily helped: switching from "block all cross-site cookies" to "block cross-site tracking cookies and isolate other cross-site cookies". After that, the feature started working.

However, after restarting the browser today, the issue returned, and changing this setting no longer helps.

I would also like to note that currently there is no way to disable or hide the "Summarize page" button, even though I did not need it initially. I tried to configure things so it would work properly, but was unable to do so.

Steps to reproduce:

Open any webpage Open the Firefox AI sidebar Click "Summarize page" Observe error 431

Expected behavior: Page summary should be generated successfully.

Actual behavior: The request fails with HTTP 431 error.

Today, I cannot even open the website!! This is what shows up:

I have an issue where I will frequently get the error pictured on random sites. This started happening a few years ago at my previous home with my old computer. It got so annoying that I had to switch to Brave browser for a while. I recently moved to a new residence, I have a new computer, and a different ISP and equipment, so I thought I would give Firefox a try again. To my shock, the issue still occurs exactly the same way at the same rate. I would say it is as frequent as 1 in 5 sites that I visit. If I hit the Try Again button 5 or so times, the site will load. The only thing I can think of that is common to the old computer and the new one is my Firefox account. Could there be something in my settings causing this to happen? I remember that I even tried Librewolf before switching to Brave but the issue occurred there as well. Any assistance or tips would be appreciated, I feel like I am going crazy at this point. xD

Yesterday I synced Firefox desktop to iPhone 13 and iPad 11. I created an account. The syncing worked.

Today I tried to access one specific website and got this message: "500 server error. Oops. Sorry. Your request could not be carried out because of an error. Please log out and sign in again". That didn't work.

I tried accessing other websites within Firefox desktop Version # 140.04 64 bit. They do work.

I don't know if this service error is something within Firefox or within Windows 10 latest update, or something else. I've reviewed system Administrative Events and there are numerous notes for 7/18/25. Many say "Distributed COM" some are Service control manager, many entries "Device setup manager". I have photos of several screens.

I've deleted cache and history (I use private Mozilla). I've restarted the laptop PC twice. No change to that website access. I used troubleshooting and that didn't help at all.

Please help diagnose where the problem is and how to fix it if the source is my computer. If it's a server problem please advise. Thank you. JHL

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).
