Does the web site go straight to the other account, or place the other user/password into the page login?

Have you tried logging off the other account?

Open the Password Manager and remove the others data. Type about:preferences#security<enter> in the address bar. Press the Saved Passwords button at the lower right.

"Remove Cookies" from sites causing problems:

Use these steps to remove saved (form) data from a drop-down list:

1. click the (empty) input field on the web page to open the drop-down list
2. highlight an entry in the drop-down list with the mouse or cursor Down key
   do not click the mouse or press the Enter key
3. press the Delete key (on Mac: Shift+Delete) to delete the highlighted entry

I can't get in to the other account at all. No one has accessed it for over 3 months...but it continues to be the primary account that pops up when I want to log in. I have to hit "Sign in with a different account."

I tried following your instructions...but nothing seems to have changed.

Thanks for trying to help! Val
