Rated 4 out of 5 stars

Absolutely positively must have for folks such as myself who have made the move from IE to Firefox. Seems to be about the ONLY major feature missing, why on earth someone would prevent me from making the choice to simply run a downloaded file versus saving it first for "security reasons" is mind boggling. Considering the fact that FF is supposed to be the "open" standard, and IE is anything but :) In any case, I gave it four stars because I'm confident that someday soon it will be up and running on FF 26.0, keeping my fingers crossed that it will be soon. Thanks!

This review is for a previous version of the add-on (3.5.0.1-signed). 

Well, I have a beta version up and running, still struggling on some machines, not sure why.
