Good extension but the development seems to have stopped. I've made a fork "Page up and down buttons for e-ink" of it.

Very good, but please add a third button to scroll to top.

This add-on should be merged with 'Top and Bottom scroll buttons' ( https://addons.mozilla.org/en-US/firefox/addon/top-and-bottom-scroll-buttons/?utm_content=addons-manager-reviews-link&utm_medium=firefox-browser&utm_source=firefox-browser ) 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 good addon! I have one wish, the option to have the buttons 1/3 or 2/3 up on right side. As it is now, buttons in the middle often interfere with image viewers, ebay etc

works perfectly! if you have an e-ink display this add-on is a must. unfortunately, firefox makes it very difficult to install non-recommended add-ons. to install this add-on you will need firefox nightly and allow for the option to add custom collections.

Works great - just tried it with the firefox nightly on android.

Is there any way to get this extension also working in reader view? for an e-reader that would be perfect.

Works great.

so great! I just want a scroller can easy pagedown and page up with no feeling, the plugin completel it.

Great addon for E-ink screens! It would be useful to add a little strip on the edge of previous page's screen. Without this it takes 1-2 seconds to find previous string.
