If you want an app that works, does what it says it does and scrolls to the top, I'd highly recommend this one. Of all the apps that scroll to the top and scroll down to the bottom, this is the one I choose to use over and above the rest.

Thanks Pratik, your app works well.

This browser addon works great:) The only thing I did was to change the screen arrows to my own arrows image, but it's a mere trifle. This addon is very convenient to work with, many thanks to its developers!

Very Good Add-On!

Excellent! The best.

Can be customized in many ways, but these are its salient features:
A rich choice of icons in many colours allows you to choose the right icon for a page background of any colour, be it light or dark or any other, always allowing for excellent contrast and visibility.
Two sizes for the main arrow (permanently visible, or hidden after a few seconds) make it adaptable to the free space on your pages.
In addition to the main button (scroll all the way up or down) there are buttons for scrolling only the visible area of your browser window. Very neat!
You can have a toolbar button only, thus keeping the web pages free; and the many icons that you can choose from make it usable with any theme or, again, any background colour.

IMHO the best of its kind.

one of my favorite add on .

Cant Firefox without it or Chrome

После последнего обновления Firefox до версии 79.0 стали слетать настройки расширения с пользовательских на дефолт. Приходится постоянно снова настраивать.

Great. one of my best add-on.

I like this extension. Works well. Permit going up AND down. Many customizations available. A must have for all the sites which do not include this behaviour.

Great add-on. Thanks.

これメッチャ便利です。

Why don't you keep past versions in history?

Почему в истории не сохраняете прошлые версии?
