Rated 5 out of 5 stars

Wonderful addon - since it is working again.

I had the Javascript-Problem. For me the solution was to set the 'javascript.enable' switch to 'true'

Go to: Tools > Options > Advanced > General and click "config editor".

Search for the javascript.enable
Set the value on 'true'
Restart TB

After the calendar has established the connection, it is possible to change the preference back to 'false'.

This review is for a previous version of the add-on (4.4.1).
