Welcome to forums !

All those questions are pretty much already answered in previous replies or some other threads… there is a great search feature up there at the top of the page, among the other buttons…

Script blocker is available in Pro version only, there is no such a feature in Home Edition. Any third party script blocker ? There is a plenty out there, you just need to decide which one is better for you. Try searching Google for possible freeware applications, I’m sure you’ll get hundreds of answers…

Cheers !
