Using 7.0.1 Unable to log into our web data base as of today. I enter ID and Password. It tells me user name is invalid. When I use Internet Explorer it works fine. How do I clear Firefox memory of ID names?

This issue can be caused by corrupted cookies.

Clear the cache and the cookies from sites that cause problems.

"Clear the Cache":

  • Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"

"Remove Cookies" from sites causing problems:

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

I know this is a dumb question, but where is the tools? I tried Options. No good.

  • Press F10 or tap the Alt key to bring up the "Menu Bar" temporarily if the Menu Bar is hidden.
  • Use "Firefox > Options" instead of "Tools > Options" if the menu bar is hidden.
