From Jeff Johnson of Underpass App Company, this works in safari in iOS and Mac.
This app stops Javascript from running on pages, and I use it to block sites that make you turn off content blockers before you can view the site.
I know sites need revenue, but random ads only annoy me, and some of that is that I edit commercials, so I know the tricks and they just annoy me! So i block them and making me turn off my content blockers annoys me even more!
This takes a little effort and a little work, but it does what it says (and some pages break when you stop the scripts), and I love it.
