Earlier quoted context omitted.
At least mention what the default hotkeys are, and what will/should happen when you hit them. On Linux, after hitting CTRL+SHIFT+R, I just get the option to launch Chrome. I come back and hit CTRL+SHIFT+R again, and it's the same option.
I am having the same issue, have you figured out how to solve it?
Have you tried shutting down chrome before launching it from this plugin?
