Thunderbird Hangs Moving Calendar to New Window Rated 4 out of 5 stars
This add-on provides a wonderful service to the Thunderbird application, making integration with the Google Calendar seamless. Make a change on your desktop and it automatically updates Google Calendar, and vis-a-versa. Everything syncs beautifully.
Only problem is that when attempting to move the Calendar tab to a new window, Thunderbird hangs and the only solution is to force close the application and restart.
It's not a show-stopper, but would make life even easier if the Calendar could be opened in a separate window from the email client.
Stopping the Provider for Google Calendar add-on resolves the problem, but at the cost of eliminating Google Cal integration.
