Probably wicked rare anymore else would have same issue, but figured I'd post what worked for me, Just in case. I really wasn't looking forward to the whole back-up, reinstall Thunderbird, Move ALL my email accounts to NEW install, and I probably would have had same issue. Not going anywhere, so I just wanna click in and read.įirefox for the WIN, It did what Chrome couldn't first attempt. I considered doing it with 2FA, as I use that for Crypto and other crap, but It's a desktop. A few hours each attempt, then had to leave it to keep my sanity haha. I couldn't believe how much time I wasted to get it to work. What is Thunderbird Thunderbird is a freely-available email client, created and maintained by the nonprofit Mozilla Foundation. But with Google is doing the Authentication, I thought I could trust their browser to be able to do it. I wonder now if I had reinstalled Chrome, if it would have worked. Was almost to the point of reinstalling stuff.Ĭomputers been in use quite a while. I help EVERYONE solve the worst problems, so I felt like an idiot that it took me so long to solve mine. Was a EE for another 10, then Had 3 computer businesses and sold each. Hate to admit it, but I taught computers for 10 years. rcprimak: 5 days ago all my gmail accounts were only allowed to login to check and send email with 2FA with the mobile googleemail app and the pc Thunderbird. A few add-ons/extensions on both Browsers. I use Chrome Mostly, but use Firefox for my multimedia.
