Scroll it!

This extension allows you to scroll up/down on almost any page to see older/newest records/news/posts/photos.
To use it - click your RIGHT mouse button on any place and select Scroll it -> select option to scroll and feel free to use other tabs while it scrolls, it will let you know when it's done.

Don't forget: if you chose infinite scrolling - you would like to stop it anytime (stop option from context menu does it).
Also it will let you know if it's stuck somewhere.

Source code is open and feel free to read/clone it from github page.
Feedback is appreciated.
