FolderFlags

Rated 5 out of 5 stars

by Umberto Celentano on جولای 20, 2026 ·

I updated FolderFlags to be compatible with Thunderbird 152.
I tried contacting the developer, but the contact form on his website doesn't work.
How can I make this update available to everyone?
Do I need to contact its creator first, or can I distribute it without violating any licenses?
