On contrary to Firefox, this add-on depends on the OS one use to work/don't work.
Because this is not even mentioned on the description (unless I'm blind), i had to install it, restart, then realize it doesn't work at all on Linux, uninstall, and restart. That's why i write a critic.
As quoted by Wylbur, being able to use one software on various places, independently from the OS that is installed there, just makes one's life easier :-)
Thank you Wylbur for mentioning another add-on which works whatever the OS is.
