ScrollAnywhere

Scroll Anywhere enables you to drag scrollbar with your middle (or right) mouse button without touching a scrollbar.
Just hold the middle button and move mouse up-down or left-right.
You can also change the behavior to simple "grab and drag" style.

Supports also Momentum - ability to throw the page (like on your phone) - including infinite scrolling option.
Now with the option to change the cursor while scrolling!

Warning: very addictive! :)

Known issues:
- does not work HERE on https://addons.opera.com/en/extensions/ (blocked by Opera)
- does not work on browser specific pages like "History" or "Extensions" (blocked by Opera)
- does not work on other extensions pages like options page of some addon (blocked by Opera)
- in Linux right click (context menu) cannot be canceled so only middle button is working correctly
