Will not accept my password Rated 2 out of 5 stars

Works fine for my Google Apps account, but will not accept the password for my standard Gmail/Google account... Have confirmed the password is correct, as I'm sure all the other people with the same problem have... Ubuntu 12.04, Firefox 14.0.1 - UPDATE: The forked version of this add-on, Gmail Manager NG, works perfectly for me. https://addons.mozilla.org/en-US/firefox/addon/gmail-manager-ng/
