Extensions Failing to Install

I am unable to download any extensions to my macbook pro. I go to the extension warehouse that is officially associated with sketchup, I login successfuly, search up window maker as that is what I want, click on the logo, button that says free, and everywhere else in the associated region that should lead to a next screen or indicate I selected, but nothing happens. It’s like I clicked and the click was a blank fire, a gun with no bullets, a mouse with no click, : (. Anyone know what is up?

You can’t install extensions on the sketchup for web anyways.
