Firefox Community Forum

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

Using Windows 11 just reloaded on new hard drive (Solid State). Old hard drive took up smoking. This error does not happen on any other site and did not happen before.

The web page I need to access, prevented by this error trigger, is my webmail. How can I direct Firefox to ignore the error with respect to this specific message?

Please reply to ********@gmail.com. (Mod's note: email removed)

Thank you!

I can not access my email account . I get this message ...

   An error occurred during a connection to login.gmx.com. PR_CONNECT_RESET_ER

Recently when I try to use the PCH.com search in their emails, I get this message; "HTTP Error 400. The size of the request headers is too long." Is this a PCH problem or Firefox and can I fix it?

Why does Firefox intermittently fail to connect to the Newsmax website? I get a Secure Connection Failed message. It happens only occasionally, but enough to be an annoyance. What's the problem and how do I resolve it?

I am not sure if I asked this previously with another issue. Be that as it may, I will ask.

A few weeks ago I went into the Startup Menu to disable certain programs that I thought was slowing the system's startup. That was a couple weeks ago. I went over the startup items and disabled only those I do not use or need after starting my computer.

I use Yahoo as my homepage on the Firefox browser. On some of the photos associated with an article I get this error:

Error in rendering player

Error Code: 400-404 Session Id: rm7bfdr3 (Pls: 93a94693-7bc6-4c95-8398-99b65521dab2)

Why is this happening and how do I fix it? I will also attach a screen shot of a page with the error.

Thanks as always, Irv

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

Firefox is not letting me access Xero.com which is my primary use of working with clients.

The message I get is

Access Denied You don't have permission to access "http://go.xero.com/app/!hQMY2/dashboard" on this server.

Is there anything I need to do to allow go.xero.com be used.
