One of the key factors behind its meteoric rise is its huge library of extensions that truly sets it apart from the rest, especially for web designers and developers.

Another key extension under this category is called Dimensions which helps to measure distances between various elements on a webpage. Its functioning is slightly different from Page Ruler. Dimensions measures distances from mouse pointer up/down and left/right until it reaches a border.
