Extra Folder Columns Rated 5 out of 5 stars

This Programm/addon is amazing good. I love to use it, BUT
In the mean time I think THUNDERBIRD SUCKS!
Do I have lack of knowlege? Possible.
I see after upgrading that addons don't work anymore. Even upgrading to 9.01 did ruin thunderbirds with addons so that I could not see any account anymore.
I hope Joey Minta is willing to adapt the program to thunderbird 9. His programm was and have to be standard in thunderbird!
Then it is vey difficult to find Extra Folder Columns. I found it then by searching fo columns!
