This extension caused numerous issues with both of my computers running two distros of Linux both Debian and Arch.. on 4 different desktop environments literally crashing the desktops. Had to go into about:config files in order to completely remove it... even after removing them from the addon page this extension continued to reek havoc and remain in firefox, seamonkey, waterfox, and cyberfox... it also caused multiple problems with any chromium based browser as well including chromium, chrome, opera, and vivaldi.. P.O.S

not working with 57.0.2

Dont work on FF Quantum 57.03 - 64 bit

it is really a pity
