No, a script blocker. Websites have scripts in them that do things like pop up ads, track your browsing, give your computer the herps, etc...
Blocking the scripts, don't even give the ads a chance you know you're there.
....and the midget porn sites too.
This is what I use..
NoScript - JavaScript/Java/Flash blocker for a safer Firefox experience! - what is it? - InformAction
On this page (and the rest of the internets) it's blocking googlesyndication.com, googletagmanager.com, microsoft.com, and turbobuick.com
I see no ads, but there's boxes that say ''JavaScript is disabled. For a better experience, please enable JavaScript in your browser before proceeding''. AKA ''can you make it so we can track your ass, fill your computer with cookies, and show you ads''.
I know this site is here to make money for the owner(s), but if I can't show up and hand out free tech advice without a bunch of BS, I won't show up at all.
When I need to refresh myself on something I posted years ago, I search turbobuickS.com anyway. That archive is 100% intact from day 1. It's dead now, but it never had the massive delete happy days, or the FBI stuff, or pictures vanishing, or any of that drama.
With the exception of Broke1's dumbass messing with Mike, it was pretty much tech in the tech section.
