Thunderbird Conversations add-on

Good morning!

I have successfully installed the add-on “Thunderbird conversations” and it’s working.
The issue is that whenever I double click on a email, to open in a separate window, the window that opens is very high (from the top to the bottom of the screen) and tight, always located on the left side of the screen.

Since is a bit unconfortable to read the emails in a window in that position and with that dimensions, every time I am forced to move it at the center of the screen and resize it.

Is there any way to change the default size of the message window?

(When I am not using the extension the windows of the emails opens normally, and if I resize or move them, the next email opens with the last parameters set)

many thanks!

The Conversations addon has a support site:

Many thanks DaverRo, I will check that.
