Thank you for your report, I've been able to reproduce this issue and I've passed it to the developers.
For now, as a workaround, please log in at https://todoist.com click on the gear icon in the top-right corner, go to Settings -> Account and use "Edit" next to "Password". This way you will set a separate password just for Todoist and can use it to log in manually through our Thunderbird plugin using your Gmail address in combination with this new password.
Note - you will still be able to log in via Google anywhere else and this will of course not affect your Gmail password.
Indeed, thank you for this information, I'll pass it to the developers too.
It seems that the source of this issue is clicking on one of the fields you need to use to enter your data. That said, for now as a workaround, please try to click somewhere outside of these fields and then use the TAB key to navigate into these field. Type in your email, hit TAB again, type in the password and hit Enter to log in.
I've just tested it and it worked for me. To clarify - you must first log in on the web using your Google Account, then go to the Settings to set a password for Todoist and then manually log in by typing in your Gmail address and the new password which you've just set in the settings using NOT the "Gmail Login" method, but the regular email/password login.

I'm stuck with exactly the same problem.
TB 24.1 + Chrome.
Tried the workaround with the password change, but to no avail.
When I fill in the fields in Thunderbird (with the TAB workaround) and hit enter, I get sent to :
and despite entering the correct password here (the google one, not the updated todoist one) it does not work.

Probably using the latest. I downloaded your extension this morning.
Thunderbird French V24.1
Is there no other way to log in than thru gmail?

When in Thunderbird I click on the Todoist button in the top bar. I then see a side pane where I am asked for my gmail login - is there no other login method?

Ah... found it - this is workaround #3!
When in Thunderbird, left pane and you see the google form, you need to right click in a blank space and say "log out". You are then brought back to the todoist login form....
That's a LOT of jumping thru loops to get there! But I'm finally in.

Same issue, good to know you're working on it, the workarounds work with me
