Almost Perfect but... Rated 4 out of 5 stars

This extension, like others have commented, is almost transparent and is easy to forget that it's installed...

But on a RARE occasion, the default download manager occasionally rears it's head up, and then I go into shell shock that this extension isn't showing.

Keep up the great work! :)

This review is for a previous version of the add-on (0.7.2).
