I use uMatrix extension for Google Chrome. It's available also for Firefox. Not sure about IE. I like it, but it's annoying sometimes how you have to fiddle around with it so much. It's either ALL or NOTHING. I wish there was some middle ground that I could simply install and have it do most of what I want most of the time. Example when I got to an eCommerce site like eBay or NewEgg I have to turn the whole thing OFF because there will always be some strange little piece of jscript that won't let me click a button to write a review, or save to wish list or send a note to the Vendor or who-knows-what. But then when you turn uMatrix OFF, then you are waiting 10 seconds for each webpage to load because you have to see that video advertisement for eharmony, or something equally stupid.
So that's pretty much my gripes about uMatrix. Good, even GREAT sometimes, but then there's the long list of "except fors".
So I wonder if anyone else has a better option. Or maybe someone has a worse solution than I do, and would be glad to know about uMatrix. Either way, I'm interested in what other people think.
