CloseReview for Theme Font & Size Changer for ThunderBird by luc_atrebas
Rated 5 out of 5 stars
Thank you so much Steve for the clear explanations and the procedure to keep enjoying this great add-on for people like me using various screen sizes and devices. I get the right font size in two clicks! Too bad Baris Derin did not bother to make the adjustment himself, he is still to be commended for offering this great feature to the community.
