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!

This was a nice extension when it worked! Unfortunately, while it'll still activate, the icon no longer does anything. The extension is entirely non-functional in Firefox 69.

It is utterly simple and useful.

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

Why does this extension need to access data from all websites? Other similar extensions do not need this permission.

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

nice
