For the last 2 months, I get this response from HSBC UK when I try to log in.

"Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit."

HSBC says that Firefox is not compatible and I should use Google Chrome etc.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

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.

You can use the button on the "Help -> More Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
