Apart from adblock and darkreader this might be the greatest extension in the history of browsers. Enables you to instantly grab and view the max resolution of an image on any website instantly with any keybind you decide.

Damn good.

Adjusting settings, I'm using it not automatically, but with CTRL keyboard pressed (for on of numerous example of adjustments)

works well.

Chrome refugee here, thanks

I spent many hours switching from Chrome to Firefox only because of this extension
