Rated 3 out of 5 stars

I confirm what reporteed from "I_am_a_Landstander", ie by using 1.3.0 beta3 I cannot open mail with attachments. I had to go back to 1.2.4.

This review is for a previous version of the add-on (1.2.4). 

Subject says it all: This bug seems to have been disappeared with the release of Thunderbird 3.1.5. Could you please check.
