Rated 4 out of 5 stars

I went from not being able to open a link in an external browser (Firefox) to having every single gif open as a tab. I should note I had to add a string in Thunderbird config (network.protocol-handler.external.http;true) to get the external browser to open, but between the two something isn't right.

This review is for a previous version of the add-on (3.3.4).
