Thank so much!

Fix this: 1) default and configured hotkey does not work; 2) turning off with the Esc button does not work.

awesome tool, helped me measuring my floor plan

This is just amazing! Works fine with Firefox 80. Thanks a lot!

It is utterly simple and useful.

muy buen addon, para quienes creamos webs y necesitamos los px exactos esta es la mejor opcion

Great add-on! But could copy the measurements when I click on the element in the page.
