400 Bad Request - Request Header Or Cookie Too Large
There's a web site I use very frequently that I suddenly cannot access any longer. I got the error message, "404 Bad Request," followed by "Request Header Or Cookie Too Large," and then "openresty/1.15.8.2." This only appears with Firefox. Microsoft Edge loads the sight just fine. What's going on here?

This issue can be caused by corrupted cookies or blocked cookies.
- check the permissions for the domain in the currently selected tab in "Tools -> Page Info -> Permissions"
Clear the Cache and remove the Cookies for websites that cause problems via the "3-bar" Firefox menu button (Settings).
"Remove the Cookies" for websites that cause problems:
- Settings -> Privacy & Security
Cookies and Site Data: "Manage Data"
"Clear the Cache":
- Settings -> Privacy & Security
Cookies and Site Data -> Clear Data -> Cached Web Content: Clear
If clearing cookies didn't help then it is possible that the cookies.sqlite file in the Firefox profile folder that stores the cookies got corrupted.
- rename/remove cookies.sqlite (cookies.sqlite.old) and when present delete cookies.sqlite-shm and cookies.sqlite-wal in the Firefox profile folder with Firefox closed in case cookies.sqlite got corrupted.
