No longer working? ++ Rated 4 out of 5 stars

However, today it seems to have quit without any warning. I've checked, and it is enabled, and I haven't changed the settings at all. Something to do with an update?
A well-working version 3.2.0 continue to use it.
Edit:
I have Firefox 44.0. 64 bit Win 7 Ultimate 4 GB Ram .Please fix it.

No longer working? Rated 5 out of 5 stars

I've been using this addon for years, and have enjoyed it tremendously over the default smooth scrolling in Firefox. However, today it seems to have quit without any warning. I've checked, and it is enabled, and I haven't changed the settings at all. Something to do with an update?

This review is for a previous version of the add-on (3.2.1). 

that's too bad Rated 1 out of 5 stars

The main smooth scrolling was working perfectly, but as it has been written before, Scroll boxes, some comments sections, text boxes, Youtube notifications, all these child elements are not working with this add-on.
So it's useless.

Does not work properly on Win 10 with touchscreen Rated 2 out of 5 stars

Good with the touchpad, but bad with the touchscreen (flicking the page stops instantly after lifting the finger).

For REALLY mind-blowing scrolling, try the new Microsoft Edge Browser :(

I wish it worked.

Scrolling is excellent, I love the fact that I can flick faster by muscling the wheel, and it's pretty good, BUT it has too many things wrong with it.

Scroll boxes, some comments sections, text boxes, Youtube notifications, all refuse to scroll, instead scrolling the page.

I'm too used to the niceties of FFx to give up localized scrolling. Also, the bouncy edge doesn't render backgrounds, but renders elements, which is kinda ugly.

I don't know if there is a way to fix it. And since the dev didn't include a fast on/off (that I could find) I'm afraid it will stay disabled.

4/5 because it's a great addon, it works, and I like it. Unfortunately, no, thanks.

Now this addon is useless. Project Silk (smoothness scrolling and zooming) is in FF 40 and newer.

Ottima estensione! Consente di avere uno scrolling sul pc simile a quello di tablet o smartphone. Estremamente personalizzabile!

It's works on my firefox 38.0.5 perfectly. Not only smother but also work efficiency. You may quickly switch 3 differ custom settings to suitable most of situation than any other scrolling add-ons.

After extensive testing, it doesn't work Rated 1 out of 5 stars

As far as I can tell, it just doesn't work. I've taken the three color options (red, green and blue) and set them to low, middle and high settings on all the parameters and can't see even a hint of any difference. When I unload it, it is exactly the same again.

It's a nice idea. I was really hoping it would work. I tried, but won't bother again.

This could be dangerous if you leave the bouncy edge feature on. Inserts all kind of code in your CMS editor window (Joomla for example). So be extremly careful and if you opt for using this, disable immediately the bouncy edge feature.

The best smooth scrolling extension, but has an important bug: always scrolls the highest element in hierarchy, even if the mouse is over an scrollable child element.

confusing Rated 1 out of 5 stars

I don't know if my inability to make FF spacebar-scroll slower and smoother was due to its confusing interface [cute but obscure naming of the different controls], or its total lack of explanation, but i couldn't get it to work.

Great! Rated 5 out of 5 stars

I used an extension like this until it became incompatible a few versions ago. I'd almost forgotten how much easier it is to browse the internet with customisable smooth scrolling.

It's good. However, the 'two finger gesture' to back to previous page on Mac OS X is broken. Please fix it. Thanks.
