Till today a superior AddOn - so many thanks for an often used function not provided by default for mouse users.
Certainly often sites do have their own button for going up large pages, but you never know where to find this button, and how it looks like, and what it exactly does (showing ads..). Fastest way (for mouse users) is always an icon of this add-on you can implement in the symbol-bar.
But recently with Firefox V45.3.0 the arrow-up-icon changed from big to the tiny one. That makes it more difficult to find between the other icons, so it would be nice if this would get corrected.
Many thanks in advance!
