In a Internet full of spam, pop-ups and annoying ads, this is a MUST HAVE for everyone (combined with Ghostery), on every device.
It just doesn't block ads, it makes every site much more readable (especially newspapers that are always full of junk).
It blocks malicious code, suspicious sites and almost eveything that shouldn't be in a webpage. It makes the everyday use of Internet much better.

It makes the web browsing smooth and clean.

Finally gave up on Chrome. Specifically because of this extension. Now I can browse w/out being bombarded by ads. FYI: uBlock's free DNS server is a must-have!

simply

One of the best ad blockers ever made i did stop using it after setting up DNSMASQ to do it

Must have to nagivate the interner safely and not get bombarded with scammy or malware ads

One of the best addons ever made. Make sure to enable everything in the filter's list to get max protection if you haven't. No idea why most of them are off by default.

Overall a wonderful blocking extension, however as of today Youtube seems to have figured out a way to punch through it. Not sure if I need to update a filter list or if it's something you guys need to take care of on your end, but I'm rating this positively regardless for otherwise impeccable function.

UPDATE: Sometime within 28 hours after writing this review, the issue with Youtube has been resolved. I haven't done anything different, so I'm assuming either one of the filter lists I'm using fixed things or (more likely) y'all found the issue's cause and stamped it out. Good on ya c:

Very effective not only as an ad blocker, but also as a malware catcher. Saved me from entering a scam website.
