Open Thunderbird - help - other troubleshooting information (please report if the English text is different)

Opens the page that in Firefox corresponds to:

about:support

In the image I have already set the level to 1 (deafult 0).

preferences - scroll to the bottom - configuration editor

It would be interesting to see if Firefox settings are possible and working

I recently installed Thunderbird 136.

Now it is necessary to check whether the client-email functionality has remained unchanged.
