Better than Chuck's extensionion "Back to top for Firefox), or any other extension that I've tried, "Top and Bottom scroll buttons" by Dm3 is a very good implementation indeed. ... Way cool!

cool add-on. my preferred settings are… size: 25, transparency: 80, window edge: 1, location: left, display: always, scrolling: smooth.

Must have with Custom Scrollbars

https://addons.mozilla.org/en-US/firefox/addon/custom-scrollbars/

Amazing. It's one of Add-ons that you'll say to yourself... "how did I live without it!"
I mainly use when I scroll down lists but ultimately need to get back to the top quick, I.e. reading comments of a video and then wanting to scroll all the way back up to view.
Another reason why i use it if I am watching a series and I am nearing the end of the list, hit the DOWN button.
Thank you for a simple but needed Addon!

As a desktop touchscreen user I really appreciate these two buttons ! I would, however, like to request an improvement in this addon; I would like to see a third button, centered between the two existing buttons. This third button would 'Go Back One Page'.

It is truly unfortunate that FireFox developers display a complete failure to acknowledge desktop users with touchscreens. Even if unintended by Dmitriy, this addon is a de facto acknowledgement that we desktop touchscreen do exist !! This addon could be expanded to respond to our need for interaction with our displays.

This add-on should be merged with 'Page up and down scroll buttons' ( https://addons.mozilla.org/en-US/firefox/addon/pag-up-and-down-scroll-buttons/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search ) and the buttons should be changed to and arranged as follows:

⯭ to top
🠅 page up
🠇 page down
⯯ to bottom

Otherwise, when using them both, there are pairs of two identical buttons.

Very well designed and highly customisable

best scroller

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

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。
