Rated 4 out of 5 stars

Runs well, except one small problem, when I start Sunbird version 3.1, two applications open, so I must close one.

I use the same add-on for Firefox 5.0 and Thunderbird 2.0.0.6 without any problems.

When I disable the Add-on for Sunbird, one application opens. I assume that the problem is with the add-on.

I run all three applications on my portable drive.

Phil
