A button to scroll to top/bottom needs access to data for all websites?
Apart from that it hanged up firefox right after installation.

Please add the option to remove the "scroll to bottom", let us choose an image for the scroll button and offer an option for the bottom right corner.

Works great!

I only wish it had a whitelist where the user could enter domain addresses for websites where the addon won't show the scroll buttons.

Also works well on mobile phone

it is very useful and you should permit this addon with firefox 78.02.It is our right to choose which addon can install or not.Isn't a free to fans browser or not.It is pitty to stop this addon.....

とても、便利なアドオンですが一部のサイトで機能しなくなります。
例えば、WindowsデバイスでGoogleフォトにアクセスした際、使えなくなります。
Androidデバイスでも同様の症状が発生しています。

Very good!

Plaese add "go to begin of page" and "go to end of page".

Works perfectly, looks exactly how I'd expect from such an extension. I too would like to see further expansion of this to include a second set of buttons for single page scroll, and maybe even different button styles of colours.

It is a nice extension, it could be possible to configure or create new buttons to scroll by one page?

Really usefull:-) Please add configuration option so vertical position could be changed.

从1.0版火狐用到50几版逃离，现在又回来了，从chrome用到火狐，感觉火狐速度快了，

On my PC, I have fully functional default scrollbar, and this add-on is not needed.

It's the Android, where Fx has no scrollbar, where this add-on is the ultimate urge!

Guess what? On Fx mobile, this addon doesn't bother to work.

=USELESS

Thanks for this wonderful add-on.
Loving this.. Using this on both my windows10 lappy and oreo android.

I am using it on Windows 10, starting with version FF 60.0.3 (it is now FF 69.0.0) and it works very nicely. A brilliant idea. Thank you. PS. It works equally well in Linux FF. The only difficulty is that on a black background it is not visible. Is it possible for me to change the color or for you to add more colors?
