AdBlocker Ultimate is the greatest. My computer started freezing up, slowing down, and when I would type the delay from when my finger hit the key to when it appeared on the screen became a few seconds. Then not all the characters would appear causing me to backspace and retype s---l----o----w. After installing AdBlocker the computer works like new again, fast, not bogged down by ADS. Not slowed down by ADS loading poorly, slowly or not at all causing script breaks and page load errors. I have blocked over a thousand ads now and probably twice that on my phone.
