Windows 10 patched, Firefox 93 (up to date).

Within the last few days, I try to open threads and get the following
Bad Request
Your browser sent a request that this server could not understand.
Size of a request header field exceeds server limit.

I don't get this message using Chrome. Any ideas / suggestions?

If it’s just Firefox it’s an issue on your end most likely a plug-in. Firefox has been having a lot of issues and laid off a huge amount of staff saying their development would be impacted. Their market share is down to about 3%. Try it in safe mode. Also make sure it’s not an htttp bookmark issue.

fwiw @ngsmith I'm also a FF 93/Win10 user and haven't had any "Bad Request" errors at all.

I'm running the same combo here with no issues, I'm also voting plugin or custom config setting.

Just to chime in, I'm seeing the same issue with Chrome over the same time period. I'm running zero add-ons. The forum will work fine for a little bit each morning, but then it is endless 400 errors.

My workflow is usually to open to the 'New Posts" filter, and then right-click, open new tab, several threads I want to read with new posts. The first 3-4 load fully, subsequent threads throw a 400 Error. On the first instance, I can refresh the page of the previously opened threads and it will load properly. After that, EVERYTHING I attempt on TCF becomes a 400 Bad Request error.

Works fine in Edge.
