Does not let you adust the dimensions once you take your finger off of the key, like you can do when cropping a photo, for instance. If the cursor starts slightly off of where you want it, you have to start all over again.

Unfortunately, it doesn't work on all websites (I'm not talking about *.mozilla.org).

Dont work in responsive mode. Not draggable.

Hi & thanxx,

for trying to make measure-it great again!
but for now ... it does nothing more or better than the already built in tool in the developer panel ?!

If you could make it:
> drag-able
> resize-able
> maybe guides

You will find a lot of fans ... inclunding myself!

cheers and keep it on!
