Can't select anything

Hi everyone
New to this. I'm following the video tutorial, but when I get to teh moment of choose a link selector this is what I see and can't select anything

It happens with every web (zara.com, Luzan.es...)

Please Help

Has your cursor also turned into a circle? It seems that you have turned on "mobile mode", probably by mistake. You can turn it off by clicking on the device icon.
