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.

Es bonita y funciona muy bien. Tiene un uso residual pero para el frontal de las webs es necesaria muchas veces.

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.

nice
