Few months ago the SmoothScroll extension was available in Chrome Web Store. But it's not there anymore for some reason according to the author.
I like SmoothScroll among the other Chrome smooth scroll extensions available in webstore. Besides tweaking more detailed scroll settings, it has easy preloaded smooth scrolling settings profiles like iPhone, Opera and Internet Explorer 9.
It also features:
- Picasa-like smooth scrolling
- Mouse wheel, middle mouse and keyboard support
- Arrow keys, PgUp/PgDown, Spacebar, Home/End
- Customizable step sizes, frames per second and more...
- Works with embedded content (PDF, flash)
- Full touchpad support
- Excluded pages list
- Pulse algorithm
It's not in webstore at the moment but you can download it from source code and put them into a folder.
Open Google Chrome > Extensions page > tick Developer mode > Load unpacked extension... > select the folder you just downloaded and now you have the smooth scroll in Google Chrome.
This extension version is 1.0.1 which is older than previous version 1.0.6 in webstore. Once it is back in webstore, you can simply remove this and install the newer version.
Or you may download the SmoothScroll 1.0.6 here.
