Il like this very useful extension.
Since today, may be with the update 1.10 feb, 15, 2021, I obtain just a blank window.
It worked well before. I use Thunderbird 78.1.1 on Ubuntu 20.10.
Thanks in advance

Hi Gunter,
Thanks for your answer.
Sorry, I have done a typo mistake, my Thunderbird version is 78.6.1.
So I have tried an extension downgrade to version 1.9 and it works. Then, a new upgrade to 1.10 and the problem of blank window persists.
The version information of 1.10 says : 78.5.0 or more. Is the minimum 78.5 or 78.7 ?
