Works perfectly. Like the fact you can change the size and transparency as well as positions to L, R, and Bottom. One further handy feature would enable a bottom position with the option of left bottom, right bottom to compliment the centre position.

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.

Fantastic addon, works perfectly except one issue.... when printing from certain websites, the up/down arrows show printed on the paper. Otherwise, five stars.

Does not work on v.60

Good for Android. Thanks!

Ein klasse AddOn, vielen Dank dem Entwickler! :)

All the advantages have already been mentioned. Leave it exactly as it is.
