(I) Don't use Adgaurd. They're PRICE GAUGING their victims. Forget they exist. (II) Dump using Safari, thanks to Apple having destroyed their Extensions system and replacing it with costly, typically ineffective garbage. (III) Using any other browser, get these extensions: (A) uBlock Origin. It's free. It's the single best of them all, not kidding. It takes getting used to. Get used to it. It's great. (B) AdBlock. This is the original. Free. Works great. (C) AdBlock Plus. It's the Free upstart tag along that added the wonderful idea of letting users block any annoying web element they want. It works great. It does not conflict with AdBlock or anything else. (D) Disconnect. This is the over-kill of Free extensions. You may find it is OVER-effective. You may want to turn it off. But keep it on hand. (E) HTTPS Everywhere. It forces HTTPS web addresses where available. Any site not using HTTPS (using HTTP only) is an antiquated and dangerous place! (F) Malwarebytes Browser Gaurd. It's free. It will, often over-zealously, stop users from going to dangerous web pages. You may find you want to override it occasionally. But keep it handy. (G) minerBlock. This freebie stops evil web code from talking over your Mac as a crypto currency mining machine. Keep it on at all times. (H) NoScript. This is a grand old master at stopping bad web code. It, like Disconnect, can be overkill. But keep it handy. (I) Phish Protect. This freebie is, at the moment, still in beta. It stops evil websites from pretending to be a good website. No faked websites allowed. Help it out and use it. (J) Privacy Guard from my heroes, Electronic Frontier Foundation (EFF). It's a gotta-have-it grand old protector from surveillance crap on the Internet. Love it. (K) uMatrix. This is yet another Free over-kill from the same wonderful developer of uBlock Origin. Keep it handy. It's great for its purpose, but can drive you nuts unless you really need its help. - - There are more! But they tend to be specific to small purposes. I'll skip them here. - - BE SAFE! Share this list and Enjoy.
