CloseReview for Theme Font & Size Changer (fixed) by Firefox user c4f548
Rated 5 out of 5 stars
I had used the earlier version that no longer works, and lately found myself squinting at very tiny print in the message pane. All the Mozilla fixes, like adding files to my profile did not work. I was thinking of just abandoning Thunderbird when I found this. I downloaded it to my downloads folder, and from there I really do not know what happened (no installation information) but it showed up as an add-on in Thunderbird, which is now back to normal. So thanks very much and please include instructions for installing this life saver.
This review is for a previous version of the add-on (64.3).To create your own collections, you must have a Mozilla Add-ons account.
