I checked that it was accurate in the Saved Passwords panel and it is. I've entered it manually and still get the error message.
When I log onto Google from any browser with this account, it accepts the password. I can then access my gmail account with no trouble. My Firefox password manager shows the same password that is rejected by TB. My Gmail Android app on my smartphone and tablet also accept my logons with the same password. Only Thunderbird doesn't. I've tried deleting my pop.gmail.com login entry and re-creating it under the firstname.lastname@example.org account.
I had a Google Security warning 3 days ago, so suspect somebody might have hacked the account, changed the password, but didn't save his new password anywhere, so I have no idea what new password he might have changed it to. I am going to try changing my entire Google password and see if this will allow me to reset the TB password, but any other suggestions would be appreciated.
I have several other gmail accounts on Thunderbird and all of my accounts use the same passwords set for their accounts.google.com under the separate gmail addresses. How do I find out what to do to fix it?
