Getting "400 Bad Request Request Header Or Cookie Too Large" when I try to open US Bank login page.
When attempting to navigate to the US Bank online banking login page ("https://onlinebanking.usbank.com/Auth/Login") I get the following error: "400 Bad Request Request Header Or Cookie Too Large". I only started getting this error since the latest Firefox update...no problems prior. Also, I have no problem navigating to the page using other browsers (Chrome, etc.).

I ended up at https://onlinebanking.usbank.com/Auth/Login with no problem.
Start Firefox in Safe Mode {web link}
A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?
This issue can be caused by corrupted cookies or cookies that are blocked.
- check the permissions for the domain in the currently selected tab in "Tools -> Page Info -> Permissions"
Clear the Cache and remove the Cookies from websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).
"Remove the Cookies" from websites that cause problems:
- Options/Preferences -> Privacy & Security
Cookies and Site Data -> Manage Data
"Clear the Cache":
- Options/Preferences -> 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 if 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 -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
