greatest extension ever created

Incredible extension considering Mozilla's continued lack of support for keyboard navigation

This extension is a must. I always use it on the PC but couldn't install it on Android until recently on Android Beta; this made me so happy. I use a tablet and a bluetooth keyboard.

The best extention to maximize my productivity

This is the best extension i have seen it completely changes the way i browse and has so many features that web browsers should have by default. Thank you thank you thank you !
