Thunderbird, OAuth2, and Gmail

Posting this here because I am not sure if it is 100% a Manjaro problem per se.

Thunderbird available in the stable branch does not seem to like Google's security token, which prevents Gmail IMAP from working all together. Thunderbird does open a window to go through Google's security steps, including 2-step verification via SMS, but the app gets never registered and Thunderbird does not get IMAP access.

Reproduction steps (stable):

  1. Install Thunderbird
sudo pacman -Syu thunderbird
  1. Input your Gmail info (OAuth2).

Thunderbird installed via Flatpak does work just fine, so it is clearly an app-version issue. Any suggestions or info you might have regarding this issue?


This issue was reported and is fixed in version 68.2.1 of Thunderbird. See the bug report here:

Until version 68.2.1 becomes available in the repositories you can try the workaround suggested in the bug report (comment #22 in the report) and see if that works.

Edit > Preferences > Advanced > General (tab) > Config Editor > search for general.useragent.compatMode.firefox and set it to true

Should have checked the bug tracker first, my bad. Thanks for the reply, that explains why it works via Flatpak (which is update to 68.2.1).
