Not working Rated 1 out of 5 stars

I use Thunderbird 17.0 on Windows Vista.
When I press export, a window appears and I'm asked to select the destination folder. When I do so, the window closes and nothing happens.

This review is for a previous version of the add-on (2.8.0.1). 

You're not the first to write that, but I can't reproduce this bug, so it's impossible for me to fix it, without more details.
Please write to my email address (you can find it in my website) and tell me:

1) which version of TB you're using;
2) the exact export you're trying to do (the folder itself? the messages inside?)
3) the error you find in error console after the export will fail (if you find any).

Thanks for your collaboration.
