I am using the latest Thunderbird 22.214.171.12426 and latest Firefox 126.96.36.19936. I am having the same issue as reported in these posts: https://support.mozilla.org/en-US/q… (funda kabanzi)
I am using the latest Thunderbird 188.8.131.5226 and latest Firefox 184.108.40.20636. I am having the same issue as reported in these posts:
I have 5 Gmail accounts that I manage for different family members. All accounts in Thunderbird access Gmail via IMAP, and are configured to login with OAuth2.
This week, Google removed Thunderbird access from 2 of the accounts, I do not know why. When I login to the accounts via the web in Firefox, Thunderbird was no longer listed under their 3rd party access. The other 3 accounts are fine.
1 of the accounts does not have 2FA enabled. I was able to re-login with Thunderbird when prompted, and I was presented with a window to grant Thunderbird access, which worked, no problem. So Thunderbird's browser was clearly recognized.
But the other account does have 2FA enabled, and that is where the problem lies. Thunderbird prompts for login, and the username and password are accepted, but when I enter the 2FA verification code, Thunderbird presents a window saying "Your browser is not supported anymore. Please update to a more recent one." (https://bugzilla.mozilla.org/show_bug.cgi?id=1677845). There is no option presented to grant access to Thunderbird. Yet, the verification did work, because my primary email receives notification that the account was logged in from a new device.
For the record, the failing 2FA account is managed by Family Link (the other non-2FA account is not). According to https://support.google.com/mail/thread/127545584/, such accounts cannot login to email clients. But that has never been a problem before, and 1 of the other still-working accounts in Thunderbird is also managed by Family Link and works just fine, so that can't be the culprit.
Also, I do have AVG installed with Email Shield enabled, but disabling that makes no difference.
Thunderbird's UserAgent is "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:91.0) Gecko/20100101 Thunderbird/91.8.0". And yes, cookies are enabled in both Thunderbird and Firefox.
Is there a way to get Thunderbird to use Firefox properly for Gmail login, instead of its own integrated browser?
