Rated 5 out of 5 stars

Got the same issue as dryang where upon launching Thunderbird a window constantly pops up asking for Google credentials. Going into Preferences > Privacy and turning on cookie tracking solved the issue. Solid plugin with good customization options.

This review is for a previous version of the add-on (0.32).
