When I click a link on a website, a new Firefox tab opens with this message: 400 Bad Request Request Header Or Cookie Too Large nginx/1.18.0 (Ubuntu). This is new behavior; it was working fine until yesterday. Can you tell me how to fix it?

Steps to replicate the issue and screenshots please. Try downloading Firefox from Mozilla, run it from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

@jonzn4SUSE,

Thanks for your reply.

I cleared the cache. Doing this logged me out of other websites I was using, but it also cleared up the issue.

Thanks again.
