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 ! ;-)

This review is for a previous version of the add-on (0.4.1). 

Thanks for the input.
I'm looking into that issue: https://bitbucket.org/balbusm/xul-ext-eds-calendar/issue/9
Regarding to uninstalling addon, you just need to remove:
where <user_id> is something like rc0g55d5
However uninstalling addon is highly unrecommended :)

Uninstall evolution-ews and plugin should work like a charm :)
