I've got a big problem installing this extension !
After the installation thunderbird didn't want to launch anymore, I just got a blank calendar window instead. And when I wanted to reinstall thunderbird it didn't do anything, I still couldn't use it.
Finally I had to reinstall the complete OS (fedora 21) with a ghost image !
Very bad indeed........be careful with this extension ! ;-)
