Using Fox 20.0.1 by way of Windows 7. Attempted to install amongst others I was installing. Error popup "Sorry, you need a Mozilla-based browser (such as Firefox) to install a search plugin." Too bad I can't attach the screenshot. Pretty dang funny. But as a researcher I was really looking forward to this.
Adds Google Scholar to the search bar like it says on the packet.
It would be nice if it had a different coloured icon to differentiate it from google search. I recommend a black and white version of the standard google icon rather than the more arcane google scholar icon used by google itself but either would do.
