I have been trying to login to my yahoo email for two days without success. I get the same error msg "Bad Request Syntax." I can login just fine in other browsers. Clearing my cache and reseting Firefox did not help. Unsure what else to do.

This can be caused by corrupted cookies.

Clear the cache and cookies only from websites that cause problems.

"Clear the Cache":

  • Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

  • Firefox/Tools > Options > Privacy > Cookies: "Show Cookies"

If clearing cookies doesn't work then it is possible that the cookies.sqlite file that stores the cookies is corrupted.

Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete other present cookies files like cookies.sqlite-journal in the Firefox profile folder in case the file cookies.sqlite got corrupted.
