This gets kind of complicated, but even though there is some overlap, Ghostery is blocking different types of trackers and NoScript is blocking scripts. I will refer you here for some basic stuff.

I stopped using Safari some years ago because there is nothing comparable to NoScript available in Safari. Firefox also has an enormous flexibility because of the number of Add-ons that are possible. I never see an ad and I only allow those scripts which are essential to the functioning of a web page.
I use NoScript, AdBlock Plus, and Ghostery in Firefox, which is my primary browser. I like to know who's knocking at my door before I open it.
Here's some basic information on using NoScript.

Btw, since this thread started where you thought the latest Java update was causing the problem, be EXTREMELY careful where you allow Java to run. It is constantly being exploited for malware, even though it constantly gets patched; that patching is useless. I have it completely disabled in the browser. You do that in Preferences>Plug-ins. I don't allow it anywhere.
