- Attempts to "upgrade" iCal calendars to its own format, and fails doing so as the iCal calendars are attached to different non-GMail addresses.
- Causes the Calendar integration in Thunderbird to behave weirdly, claiming unprocessed events have already been processed.
- Doesn't allow changing which E-Mail address a Calendar is assigned to.

I don't remember why i installed this, but it's probably never helped me.

This review is for a previous version of the add-on (102.0.0).
