It's a known bug in Thunderbird. It's fixed in the latest 68.2.1 release: see https://www.thunderbird.net/en- US/thunderbird/68.2.1/releasenotes/
In the meantime, until a version of Thunderbird with the fix is available for Ubuntu, there's a Mozilla support thread: https://support.mozilla.org/en-US/questions/1271710 that in turn points to this GitHub issue: https://github.com/kewisch/gdata- provider/issues/26#issuecomment-547994463 (whew!) that finally (whew!) suggests: "Changing "general.useragent.compatMode.firefox" preference to true fixes the issue, google authentication works again." ** Bug watch added: github.com/kewisch/gdata-provider/issues #26 https://github.com/kewisch/gdata-provider/issues/26 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1850651 Title: Authentication constantly re-requested for Google To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1850651/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
