Had to create a Firefox account just to rate this extension. I've used it so much and could no longer imagine being without it (browsing using other people's PCs feels like a pain now). Like earlier reviewers have said it really should be a default shortcut in Firefox (and other browsers too). I'd give 6 stars if I could.

This deserves to be a recommended addon

it works as expected!

Great!

It's should be in firefox shortcut by default.
Thank you, save a lot of time.
