CloseReview for Theme Font & Size Changer (fixed) by DavidGB
Rated 5 out of 5 stars
Great. After updating from TB 52 to 60, finding the previous version of this add-on didn't work and not initially finding this updated version, I thought I was going to have to go back to TB52 just to have the TB interface readable. Found this update just in time. This really is an indispensable add-on providing features Thunderbird should have built in (and it rather beggars belief that it doesn't). For me TB is not usable without this on a 1920*1080 laptop screen.
This review is for a previous version of the add-on (64.4).To create your own collections, you must have a Mozilla Add-ons account.
