good extension
(but its missing option to change color of arrow :c )

It works on duckduckgo.com, facebook.com, amazon.com but not on …addons.mozilla.org!
And that’s strange, as in the domain without prefix mozilla.org it works perfectly.

I used to use another addon in which the scroll to top/scroll to bottom were items in the right click context menu, but I decided to give a go at this one, and I am quite pleased.

A scroll to bottom feature would be welcomed, as others already pointed out quite abrasively, leaving a one star review.
Or maybe another addon altogether? In the end it just makes a button with the instruction Ctrl+top, having another one with an upside down icon and Ctrl+bottom would be an easy thing to do, I think.

Thanks anyway @nullpilot, I like this and it’s definitely a "stay" item in my addon list.

Oh, it’s working on Firefox Nightly 63.0a1 (2018-07-10) (64-bit).

Doesn't work in Firefox for Android 58beta

simple, attractive - perfect!

(if people want a back to top AND bottom button, there are plenty of other extensions that will do that. rating this one poorly because it doesn't do what it never claimed to do kinda sucks.)

Adds GoTop to menu, but doesn't work in FF 55.0.2 in droid 4.4.2 - no response in any page

After update it's perfect. Looks great in between the reload and home buttons. Thank you!

Seriously, I hate when I'm scrolling down the page and at the end of it there is nothing that can bring me back, this does the job!

Is working as described, is liteweight and the button is simple, yet beautiful.
