Super Adblocking features and easy to use with lots of filters.

I can't imagine using any web browser without this add-on. Static filters and dynamic filtering makes it very powerful and fairly easy to use.
Last but not least, developer is a well known reputable person in the business.

Best Ad Blocker Extension

The internet looks weird and terribly corporate without this.

UBlock, yes.

GOOD

I cant imagine a online world without it....

THE BEST

Indeed, all my Ads are gone. There are a few (very few) sites that stop working the way they're supposed to when the ads are blocked (example and online gaming site where the games were blocked along with the ads, or simply didn't function without the ads), so on those I have to deactivate UBlock. All in all a very pleasant and useful tool.
