It works like a charm in Android Nightly. However, when both Android scroll up/bottom extensions installed, the "bottom" one would be above the "up" one in extension list. Could you swap their positions in the future?

It would be more handy if it appears straight in the website, a scrollbars like in opera would be great. I really miss that! I wish opera and Firefox mobile would work together to make a good mobile browser.

Ok

Used to work well, but now it doesn't work for me on latest Firefox for Android Nightly.

Works exactly as advertised on the latest version of Firefox stable for Android. The companion app "Android scroll top" is very useful and also works perfectly.

Unlike the given screenshot it's 3 step method. 1st click on the 3 dots, then "Add-ons", then "Scroll to bottom". It's always under the Ad-ons not under 3 dots. Thought no problem with its functionality.

Doesn't work on Firefox new tab page and maybe others, but works on websites. However, the menu option to scroll dissappear after closing the app. Going to addons page and disabling then re-enabling puts menu entry again
