Essential for web browsing. Rated 5 out of 5 stars
If you install this, web browsing gets a lot better as ads are simply removed; you never see them. It used to "only" block about 99% of ads, but now it's very nearly if not exactly at 100%.
Note that some sites rely on ads to pay the bills. If the site doesn't have a huge corporate backer (GameFAQs is owned by CBS; Reddit by Conde Nast, for example), consider white listing that site if their ads aren't a real bother. And it's great that we have the choice, to opt in or stay opted out of ads.
