The basics of Web advert-blocking in the Google Chrome web browser. Just install these (they’re all free)…

AdBlock for Google Chrome. (Update, Sept 2012: Adblock Plus replaced here by the normal AdBlock. Adblock Plus project has not been updated since April 2012, while Adblock continues with regular development).

Disable Text Ads — disables text ads, from providers other than Google. A little old now, but still works.

YouTube Auto Buffer & Auto HD & Remove Ads — removes the overlay ads from YouTube videos. You now need to manually download and install this in Google Chrome.

Facebook Purity — removes games and other useless cruft from Facebook.

Remove all “social” buttons on Web pages — removes “like” and “share” buttons for Facebook, Twitter etc, that slow down the loading of Web pages.
