  • We do not need NoScript anym more. uBlock blocks both ads and scripts. So if you activate "advanced mode" uBlock has 3rd party scripts and frame block features.
  • A fantastic extension! Uses less memory and CPU than other ad blockers. This is now the official uBlock extension, transferred *voluntarily* to Chris and Alex from the original developer (Gorhill, who didn't want the burden to support the users, and then changed idea and created uBlock Origin). Why do people keep complaining about this? Just use this one!
  • µBlock is an amazing add-on! I recommend it to everyone I meet. While it can function as an efficient ad-blocker, its true power lies in its "advanced mode" dynamic blocking ability, which combines addons like RequestPolicy and NoScript. Only load the content *you* want, not whatever third-party scripts and tracking images marketers and data miners want you to.

    Also: A special thank you to Chris Aljoudi (and Alex Vallat) for taking over maintenance of this add-on at the request of the original primary developer!
  • Muy buena y útil!
  • 很好用!开源产品没有必要在意是否官方。
  • 1. I don't like the UI. Not user-friendly at all. I need to read FAQ to find buttons of settings and explanation of the dynamic filtering table.
    2. Most importantly, no filtering list (ctrl+shift+v in ABP). You can't disable certain filters in the list. Without this feature I can't use uBlock.
  • самый лучший блокировщик рекламы
  • uBlock got it. It's the new most effective ad blocker for this era.
  • Oh my god!! I had ads on every page I would go on that I couldn't get rid of. I downloaded pretty much every ad-blocker I could find, and then I came across this one. This is the best Addon ever!! I highly recommend this to anyone with ad problems. It got rid of all of my annoying ads! I owe it to this!! <3 <3
  • this is old version. now new version is Due to Mozilla's review process, the version of uBlock available from the Add-ons homepage is currently often outdated.

    update: adfly error i must disable it
  • Need I say more
  • Better than ABP. Not only does this work perfectly for blocking any ads, but you can add any other elements you want to block. Or if there's a website you want to support through ads, it lets you turn it off for that one page. It's definitely lighter than ABP so your Firefox runs faster. I'm sure it'll only get better as it keeps getting updated.
  • just followed adblock edge recommendation about abandonance of my favorite blocker, first impression: way better configuration!
    but, how the heck to disable the page inspector??
    but, still absolutely like.

    Edit: quick responding, very good.
    This was the point. one star more to give.
    I did not see quit button for first use, but escape as usual does the job. Thanks for developing this!
    To exit the element picker, the easiest way is to press the Escape key. Alternatively, after selecting an element, click the "Quit" button in the picker box at the bottom right.

    If that's not what you meant, please raise an issue on the github page and someone will be able to assist you further.
  • Blocks adds, and is lightweight. I used to use ABP, but now i use this and it works pretty well.
  • Diğer engelleyicelerden daha fazla reklam engelliyor ve daha az kaynak kullanıyor. Mükemmel.
  • Before ublock I've been using two different extensions, one for blocking ads and one for removing unnecessary elements on pages. Since I'm not a tech-savvy person I'm glad I found this all-in-one easy to use extension and won't have to hog my computer's resources anymore.
  • It seems to have some fairly extensive settings which I only recently found(show dashboard button in addons when you click options next to ublock). There's one glaring problem for me though. It doesn't seem to have any quick(or obvious) ability to unblock ads based on domain alone. You can unblock per webpage, but that won't effect anything as you navigate through a website. I was able to make certain whitelisted webites fully unblocked only because I knew that "*"(star) is often used as a wildcard symbol, edited my whitelist, and tested it out accordingly.

    A nice fix for this would be a checkbox to change a setting to allow ctrl clicking unblock to unblock the full domain.
  • Memory consumption performance is way better then of ABP or Adguard. One may think it has little configuration options because all are on the Options page - and it's huge.
  • Perfect in firefox mobile and desktop
  • Лучшее из всех протестированных мною аналогичных дополнений.
  • perfectly well does what it says, and wastes no resources
  • Excellent first impression!
  • Personal tests show ublock using 1.7 MBs after over 24 hours of my browser running. Adblock Plus was using 15 MBs. That may seem like a big difference, however it is not. People claiming it makes your browser faster must be on extremely old PCs or have other conflicts with Adblock Plus. I've done hundreds of real-world tests going on websites I do normally using a tool that measures page loading speed and the difference was none. Sometimes the pages would load faster with ABP and sometimes it would load faster with ublock. I took a star off because the description feels like the author is trying to claim this add-on is factually faster than ABP when it's not; again it makes zero difference on several of my PCs that are 3-5 years old. The other star I removed because I felt the interface was terrible, but this one is more personal to my tastes and some people may prefer it. I had to restart my browser 3 times just to get the tabs in the options to actually work. Clicking on them did nothing at first.

    edit: There's also reviews claiming that ABP requires separate add-ons to remove pop-ups...Completely BS lies. Been using it since it came out and have never gotten a pop-up and I don't have any other add-on for adblocking (except ublock, which is what I'm using for the next week to give it a fair chance to prove itself). I don't think reviews should contain lies about the competition.

    I will re-review this in a week or two after further use.
  • Best adblocker I've used on any browser/OS. It even have many of the features that other adblockers only feature in extra addons. Highly recommended!
