Just registered here in order to rate this very useful extension and propose a feature.

I use it with a Thinkpad X200T convertible (stylus screen, no touch). I use the experimental left click option and it performs quite well. The only problem is just that when the cursor is not completely stopped while clicking on buttons inside websites (which are not text fields), the extension interprets the click as the beginning of a scrolling gesture and clicking fails. I have two proposals to tackle this problem:

1. An easy option to switch the extension on and off (a switch directly in the context menu of the extension's icon in Firefox's toolbar). I only use it in the tablet mode so I would like to switch it off in laptop mode.
2. An (adjustable) threshold of a minimum cursor speed which leads to the beginning of a scroll gesture. If the cursor is not fast enough, the mouse down event should be considered a click, not the beginning of a scrolling gesture.

But other than this minor problem the extension works very well!

Works great, really like the numerous settings. I'm using this on my Linux laptop which doesn't support OS-wide touchscreen scrolling yet, so this is perfect for Firefox.

I'm using this for my FF linux which doesn't support touch screen gestures yet. I'm using the experimental left click to scroll option seing how the touch only has that capacity in FF. It works more or less smoothly and alot of effort has been put into this extension. My only issue that to get left click scroll you have to sacrifice some of the ability to highlight. It would have been nice to have a non-keyboard centric way of disabling the scrolling, a button for the top bar for example.

Je retrouve la possibilité de pouvoir faire défiler une page avec ma souris sans utiliser les barres latérales ni la roulette.
C'est super agréable.
Néanmoins, quand je suis entrain de taper un commentaire Youtube, je ne peux pas cliquer dans une partie précédente de mon texte : mon curseur ne veut pas s'y insérer, je dois désactiver l'extension pour avoir de nouveau mon curseur repositionnable à souhait.

Works great so far! Thanks! So far I was using "Grab and drag", but sadly it does not support Firefox 57+ at the moment. Luckily, I found your add-on and it's nice that it has virtually the same capabilities.

I have a suggestion that you may implement in a future version:

When a page is being scrolled up or down with the infinite momentum enabled, it will be helpful if we can dynamically control the speed of the momentum by rotating the mouse wheel (scroll wheel) up or down. Example: If we scroll the page so that we see the content from top to bottom direction (scroll bar goes from top to bottom), rotating the mouse wheel upwards will decrease the momentum speed depending on how many "steps" of wheel rotation where used, while rotating the mouse wheel downwards will increase the momentum speed. This could be optional so that people don't get upset with the changes to something they already got used in the past. Also, it will be nice if the upwards/downwards action can be reversed, because some people may prefer to increase or decrease the momentum the reverse way. A left-click, middle-click or right-click will stop the movement of the page.

Great alternative to Grab and Drag.

Круто теперь и левая кнопка есть и всё работает!!!

good!

Great extension, as graphics tablet user there were two extension crucial for me to switch to 57. This is one of them. Thank you very much for creating it!

Great addon, works like a charm, with every aspect adjustable and customizable.
In the known issues, I'm missing one "page" though, where it somehow doesn't work: Reader Mode.

Exellent replacement of Grab & Drag plugin

很喜欢这个扩展 用鼠标左键代替滚轮下翻页

Tell me whether you can add auto-hide scrollbar as in the extension Scrollbar Auto Show / Hide?

i have Firefox Android and it doesn't works

I'm using it with my tablet pc and computer with digitizer pen and I think it is better than almost every other competitor add-ons available right now.

Function Request :
How about adding a quick toggle button?

very helpfull addon for me, i have donated

I was using the (left) click and scroll option, experimental I know but, it was impossible to ''reposition'' the cursor in the comment box...Other than that, the add-on works good.

Performance problems solved by enabling the advanced option "Don't lock i-frames when scrolling"!

Just love it!. It does exactly what it needs to do.

If you find an annoying clash with URL Paste and Go on middle click, check my previous comment.

Legit there isn't any complains or issues I can think of from my experience with it, it just works!
You can add momentum, control the speed, reverse, change cursor, and it's extremely light and simplistic, I just love it performs great.
Only legit problem I have with it is something out of the developer's hands, which is it doesn't work on firefox official pages like this one... or the option/addon pages, just cause I get so used to it because of how smooth it works, I actually feel like that's how you use pc, I forget sometimes that other pages such as a folder or chrome do not work like that lmao (it's not really an issue just worth pointing out)
Anyways thanks for this amazingly useful addon, here's your well deserved 5 stars <3

Really useful and works perfectly
