Working great in Firefox 79.0b9
However, in Private Browsing (run in Private Window permission = Allow) it stops working.

nice

Please make a dark version. Currently it looks terrible with Firefox dark theme. Otherwise, 5-stars extension!

Pese a ser bastante fea y tener un diseño tosco que no ha cambiado en mucho tiempo (quizá es una posible mejora importante), su utilidad y funcionalidad sigue siendo de gran ayuda. Muy útil.

Have always enjoyed using this - although better when it was simpler and didn't move the page around.
Just the eyedropper and an info bar.

I removed from my screen by mistake, how I get it again in my laptop screen?

très bien

easy to use
