Scroll to top not working in FireFox

[vinuel]

I’m using the addon to have a simple scroll-to-top on my site. It works great in Chrome and Opera,
but nothing happens in FireFox (Windows, FF 51.0.1).

Just FYI: I fixed this by putting the following to my CSS:

@-moz-document url-prefix() { 
	html { overflow: hidden; height: 100%; }
	body { overflow: auto; height: 100%; }
}

@vinuel thanks for the workaround, however, this breaks other components using scrolling (in firefox)
