two improvement could been made for better browsing experience

1. one button click for only one page up or down instead of top or bottom, so that long page easier to read. it need an other arrow icon, movable along the screen edge by dragging to mark a distance from the bottom of the screen to show how much of a full screen to be scrolled up or down for one click. so that it just scrolls only one page of scrollabe content for each button click. the mark is needed for pages with fixed header or footer permanently occuping top or bottom part of the screen that is resistant to be scrolled.

2. continuous button pressing scrolls page quickly till top or bottom reached.

Would be great if you add the possibility to have 2 additional (and optional) buttons to go up / down for 1 page only.

Works great on Firefox for Android but not so good on Firefox on the desktop because it interferes with the right-side scroll bar. If the icon was positioned just a little further to the left, it would be perfect.

отличный аддон + ничего лишнего

I click on it and go straight to the bottom of page. fast

Best one I've found for Android so far. The ability to modify the location and opacity is great. I only wish that I could place it in the lower right hand corner.

Great add-on for instantly moving to the bottom of each page. Would be perfect if there is an option to scroll to bottom/top of all open pages/tabs. Thanks again.

It's a very good Top/Bottom addon (oups...webextension).
I appreciate all the options it provide too
Thanks....
Make FIR quantum better

i wanna that btn always display show duble, up and down.

and this location how to put right-down ?

nice add on, i like instant scolling mode, spare much time :D

Perfect! :)

Does the job but should be able to manually interrupt the scrolling but unfortunately you can't, so having said that there is definitely room for improvement.

Отличное расширение. Однако почему-то не работает на некоторых сайтах, напр., forum.ru-board.com. Нажимаешь на кнопки, и ничего не происходит. Но на большинстве сайтов работает без проблем.

Don't work with Firefox 57 on Android

Ganau so etwas habe ich gesucht. Funktioniert prima. Einstellmöglichkeiten gut und für mich ausreichend.

Works as described. Super useful. Makes it easier to navigate long pages.

It works annoyingly weird on Wikipedia and Twitter mobile site.

Not on android

Works well in FF 55.0.2 droid 4.4.2
Needs long hold facility to hide buttons or Disable addon.

It works, but it scrolls really slowly and the are no custom options
