Good ideea, but not working at all! Rated 2 out of 5 stars

It is quite useful sometime to be able to see the correct(actual) memory usage of each add-on(specially enabled one). Unfortunately on FF 44.0.2 this add-on is not working at all. If, in the future this idea(to see add-on mem usage) will work correctly without doing other damage to the functionality of FF,OS,networking....,I will change my review and give it a 5 of 5.
