Rated 2 out of 5 stars

I can use this extension only for my personal calendar with a limited amount of recurring events. The work calendar uses Google Apps and contains a huge amount of events, mostly are recurring ones (daily standups and weekly reviews, plus the ad-hoc meetings... every day is filled). This extension unfortunately doesn't scale very well and occasionally I get unresponsive script alerts that freeze Thunderbird, preventing me to use email and calendar productively.
Sadly, there isn't anything better on Linux at the moment.

This review is for a previous version of the add-on (1.0.4).
