I use this for years and I'm very happy with it. Thank you very much!

Consumes a lot of CPU, sometimes browser freezes, also picker does not function right, the top bar that appears pushes the page down causing a jumbled effect.

Looks like it just doesn't work with the latest Firefox. Read (and believe) the negative reviews; any remaining positive reviews are clearly for an older version.

Thank you for your work.

Es genial. La utilizo mucho para el desarrollo web.

its not work

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