Rated 4 out of 5 stars

Any idea why in Thunderbird 68.12.0 (on Windows), the HTML tab is displayed with yellow characters on yellow background ?
That being said I could edit it after transfering it in the notepad, but it could be more handy.

This review is for a previous version of the add-on (3.1.9).
