CloseReview for Theme Font & Size Changer for ThunderBird by HackerKitty
Rated 2 out of 5 stars
Thanks to the detailed instruction by mrx2020, I managed to make this indispensable add-on working again. The trick is to compress the files within the folder not compressing the folder itself. Took me sometime to figured this out. Also the comment out is done with // (double back slash) not # (like in bash).
This review is for a previous version of the add-on (62.0).To create your own collections, you must have a Mozilla Add-ons account.
