A nice extension. Generally works but occasionally has hiccups.

That said, updating to the newest version needlessly cluttered up my context menu with duplicates of the stuff available through the browser action (that I currently have to resort to userChrome.css to remove) and non-optionally added a requirement for notification privileges with no option to turn off whatever annoying popup it's planning to display.

I'm giving it a 3 out of 5 for those warts.
