Rated 4 out of 5 stars

Using Vista Business, TB 2.0.0.19. Works really nice, but if the option to load contacts at startup is checked, sometimes TB will show the stop script warning. Below how someone solved the problem for other plugin:

"A bug very similar to this was fixed in the latest release of the Zindus Thunderbird addon.
The bug only affected users with a) large addressbooks and b) slow computers.
The fix involved breaking up one big job into a number of little jobs using Iterators:

and between little jobs releasing control via setTimeout(0).

This review is for a previous version of the add-on (0.5.12).
