It could be native, like Opera browser! Rated 4 out of 5 stars

Good job dude! This extension is amazing, everything works perfectly! The only thing I want is a one-pixel black border around the picture frame as thumbnails in Windows 7 taskbar, it's more aesthetically pleasing because it gives the impression of a more well-rounded work. But it's just a superficial flaw, everything else is perfect. Congratulations!

This review is for a previous version of the add-on (1.1.7).
