Excellent! But broken with Ubuntu 15.10 - no Events show in Calendar Panel.

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

Thanks for the input.
Issue has been fixed in version 0.4.2.
It takes some time for Mozilla to evaluate the addon.
Feel free to download it for Support Site - it is a Bitbucket space where you can raise issues or download the addon.

...in Ubuntu 14.04 and Thunderbird 31. No start up problems or delays. Events immediately sychronized after installing the addon and restarting Thunderbird.

Thanks!

Great plugin, after workaround it works on Fedora 21. All local calendars are exported to Evolution and visible in embedded Fedora calendar. Thanks, good job :)

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 ! ;-)

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:
~/thunderbird/<user_id>.default/extensions/{e6696d02-466a-11e3-a162-04e36188709b}
where <user_id> is something like rc0g55d5
However uninstalling addon is highly unrecommended :)

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