  • Have been using this for a few weeks and is excellent, pleased to see it`s finally on add-ons site. Thank`s so much.
  • W porównaniu z AdBlock i AD+, same pozytywy. Niesamowicie prosty w obsłudze, bardzo skuteczny i nie pożera zasobów jak AdBlock. Bardzo łatwo uzupełnić blokowany element z menu, bezpośrednio na wyświetlanej stronie. Wcześniej pod FF używałem bezpośrednio z GitHub, od wersji 0.7.cośtam. Nie zauważyłem żadnej nieprawidłowości w działaniu.
  • now my go to adblock.
  • ad block+ gpl3 = awesome
  • Blocks Google's AdWords & AdSense Ads. Blocks video ads. Fast and reliable.
  • Actively developed with open-source on github. No problems here.
  • +1 to previous appreciative review.
  • I have tested this on many different computers and configurations and on every single one I can immediately see the improvement in performance compared to e.g. Adblock Plus, regardless of how powerful the system is.

    µBlock is blazing fast even with 160 000 filters compared to ABP with 89 000 filters, a lot less jank and jamming, faster startup... Its amazing. Not to mention the improved blocking power, ability to block and examine behind-the-scene requests, the local caching feature if we get it back...

    The only drawback is that the UI is less powerful and less informative in certain ways and there is no built-in subscription issue reporter. But I can live with the certain UI drawbacks, since the performance, blocking power improvements and other features make up for it tenfold.

    The authors are also proactive and eager to improve the addon and I like their honesty. Cant wait to see this addon mature further.
  • Great to see uBlock now on the FF-Add-ons homepage.
  • Great add-on! I couldn't install it on my phone though. Firefox on Android said the add-on wasn't compatible.
    Which is true. The extension has proper compatibility from desktop Firefox 29.
    However Fennec support may be added in the future:

  • На некоторых сайтах µBlock не хочет соблюдать "мои фильтры" после перезагрузки страницы! Откатился на 0.8.6.0- там всё работает!
    If you have a reproducible problem, you can open an issue and describe it here:

  • Very fast!
  • definitely the best ad blocker out there regarding performance and efficiency
  • By far the best ad blocker. Much lighter than Adblock (Plus) both objectively and subjectively, without sacrificing functionality. The author deserves only superlatives.
  • It does his job with less RAM and CPU consuption :D
  • Super efficient and highly configurable, great job!
  • Love it! Getting better and better!
  • best
  • Very happy to see this in the official add-ons directory.
  • Couldn't be happier to see a lighter weight ad blocker. All of my friends will be getting this as soon as I see them.
  • logged in here to give a review of this addon. This addon has been light on my resources and it has been the best adblock I have ever used. Could not ask for a better adblock/malware blocker.
  • Very good. I have an older machine and find it is quite a bit quicker with uBlock compared to Adblock Plus.

    Ad removal seems to be just as good as with Adblock Plus too.

    Can't think of a reason not to use this over everything else.
  • I recently disabled then enabled my extensions one by one and realized Adblock Plus was the culprit that was freezing my browser and making it unresponsive. Now... don't get me wrong, Adblock Plus has been installed on my Firefox browser as long as i can remember and has always done the trick, but as of late it has been acting a little bit too buggy for me, especially knowing it has been causing my browser to trip out. Now, since installing uBlock i have not had these problems and my CPU usage levels has drastically went down. So for right now, i'll say uBlock is doing what it says it does and maybe a bit more.
  • Signed up to Mozilla.org just to say - As a resource-cautius user, this addon has been a nice addition to my browser. I've been using this addon for the past few weeks and my experience has been delightful. Thank you for developing this. In my opinion, such an essential addon deserves to be featured.
  • uBlock bocks all ads and most trackers by *default* which makes it by far the easiest thing to just recommend to most users who are new to this whole concept. Besides that, the advanced mode is superb, the UI is great, and it's under continuous development, with lots of improvements on the way. Upcoming versions (as of this review) effectively replace the separate RequestPolicy plugin for truly advanced control of all third-party requests.

    This is the ONE plugin I now recommend to absolutely everyone.
