Review for Thunderbird Message Filter Import/Export by alberto.villar
Rated 4 out of 5 stars
This has been a very useful tool during these years. One could keep collections of filters and also transfer them among different computers / accounts. Now with the latest Thunderbastards versions the tool no longer works.
I'm rating 4 over 5 because it's an easy of use and very solid tool. I'd like the developers to update the add-on, if possible. I'll rate 5/5 then.
To create your own collections, you must have a Mozilla Add-ons account.
