Measure-it

Not working in my chrome..

I don't Know Why but this extension stoped working in my browser. I am using chrome

You cannot measure the width to the right page border, the size number is hidden outside the page.

Does not work.

Seems to work as promised for me

Does not work. Clicking the extension icon does nothing.

Try it in Browser Mobile Mode. What a fail....

Not working on Tablet and Mobile Mode.

Works fine on a static page, but doesn't work when a modal window in opened on a page.

Doesn't work in responsive mode when touch simulation is on. By the way, I think such a tool should be an integral part of Chrome Developer Tools, like it is in Firefox.
