It's simply the best of its kind. I have it on my other browsers too, currently Firefox 61.0.1, Opera 55.0.2994.44 and Chromium 68.0.3440.106 on Linux Mint 19 Cinnamon 64-bit (26 August 2018).

Great customization and works perfect.

Полезное и удобное расширение, спасибо авторам:)

That's what I was looking for.
Thanks man.

Makes navigating web pages a breeze. Thank You!

I love this add-on v 4.7.5;

if you have problem then reinstall or recover firefox extensions settings.

on 32 bit works well v 4.5.
I had problem because firefox sync while transparency from another machine works under 32bit on v4.5

Works great on desktop. Highly configurable, easy to export and import settings. One star off only because it's no longer compatible with Firefox for Android.

A very useful and eye-catching extension that does more than just go to top or go to bottom. When one hovers over the on-page icon, it shows page-up and page-down. Well done.

Saves time.

v4.7.5 will install on ESR 52.6.0 (32bit) but doesn't work. had to go back to 4.5.5

your homepage resolves to: Project web is currently offline...

très agréable, difficile de s'en passer, mais parfois n'apparait pas sur certains sites

it's nice and very comfotable

Been using this extension for a number of years now, mainly on Google Chrome but recently gone over to Firefox Quantum (58). For some reason this extension does not work on the BBC WEATHER page. It appears at the bottom right (My Setup) but does not send the page back to the top when clicked. All other sites work fine. Not a big problem as most of the info is at the top of the page.

Does not work with Firefox Quantum 58

very nice :)

You have to write about the capability to scroll down one page or up!
This is also very important!
But there is no option to change the score of rows when scrolling down 1 page: Sometimes it is better not to scroll down a complete side but some rows less so one can better read on beacause you can see also read lines of text :)
This option to change the page length would be fine.

thx

Great tool, works perfectly and highly configurable.

Very good. Thank you!

Please add support mobile firefox!!

Simple, elegant, convenient. 10/10.

I just have one recommendation: option to customize the button using CSS. Then it would really have been awesome!

Great add-on!

However, I've noticed something:
I was updating my blog on WordPress. My up&down arrows are vertically set and they were very close by the WP Update button. Despite I clicked the WP Update button outside of the up&down arrows, the WP Update button didn't work whatever I tried. (Also, on that particular WP edit page there was no place to move the frame away from the arrows.)

I think there are more blind spots around the arrows than I thought.
