Review for Manually sort folders by Patuta
Rated 5 out of 5 stars
Unfortunately Manually sort folders 2.0.2 excludes local folders from the accounts sorting order. Meaning they remain on the bottom of the folder pane. Annoying.
EDIT: Meanwhile I've learned it's caused by Firefox 68. Hope msf comes back.
