I'm using Thunderbird on Linux Mint. The installation is the same one I've had for awhile, with two email accounts in it, one being GMail. Today I changed my Google password. I expected Thunderbird to prompt me when the old password failed; and it did, except the window it showed me was entirely blank, except for a URL bar at the top which was to Google's domain. I tried it several times, same result. I closed Thunderbird and restarted. This time the window prompting me about the GMail connection had stuff in it, but it showed a Thunderbird logo and seemed to want me to "log into Thunderbird" or something (not Google). I think I clicked a button to advance through that screen and something else went wrong, IIRC. I decided to just delete the GMail account and rebuild it from scratch. In "create account"; it succeeds at finding a configuration for GMail, where IMAP is selected over POP3. I press the "Done" button, but a yellow bar becomes displayed: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsiMsgAccountManager.createIncomingServer] And it also says "Checking password..." with a spinning hourglass that never resolves. Any thoughts?
