Description
Check the measures of components can be easier than open the dev tools and check the size of a component.
With the simple ruler extension, you just click and move your mouse over the components to see the width and height.

Okay for measuring the page but not elements on the page

it's pretty good, but there should be a way to move the buttons out of the way. I can't measure something in the header cause the ruler size button is hovering over it.
