  • (2023-03-06) Igor Arnautovic: This app works fine, but still breaks allowed pages, making them unusable. I blocked all social media sites except LinkedIn for example, but LinkedIn appears to have broken CSS. Please fix this! And in Google Images images aren't clickable.
  • (2023-02-17) Madi Beep: hum...je m;abstiendraisde poser mon avis , vu que la lberté d'expresson n'existe plus
  • (2023-01-29) David Osipov: I'm a cybersecurity enthusiast and I noticed, that once I find a brand-new phishing website, which is completely undetectable by all antivirus vendor at Virustotal, alphaMountain a9 becomes the first to detect it right away in about 2-6 hours. Only after that other AV vendors will slowly come to detect the phish website in 3 -4 days and even more. I don't know how they manage to be so efficient - a miracle to me. I highly recommend everyone to install it - already installed at family members' PCs.

  • (2022-11-12) Clemente Núñez Bolinches: muy facil de utilizar
  • (2022-10-26) Марк Сердюков: Лучше из тех, что я пробовал! Бесплатно и качественно защищает от просмотра порно и остального контента, который портит мой мозг, ухудшает мотивацию и разрушает личность ! Всем добра !
  • (2022-09-10) Abysmal Sentinal: very useful and very nice extension for windows 11
  • (2022-09-03) Jonathan Estrada: This is the best content blocker. Absolutely love it and helps my productivity so much.it even restricts youtube comments which i always spend way too much time reading
  • (2022-08-27) Lee McCall: This is the only extension I found that allows you to switch on SafeSearch for browsers, but not for YouTube comments and also allows you to password protect your setting. The problem with this extension (as with all Chrome extensions) is that you can't prevent the extension from being removed or switched off. There is a way to do this however, by adding an registry key for Chrome which creates a Chrome policy and prevents the extension of your choice from being removed or switched off. I'm using it, and can confirm it works perfectly. https://stackoverflow.com/a/73513989/5402501
  • (2022-08-03) Mad Max: best adult block extension
  • (2022-06-08) Matthew Walsh: This is what you need. Stop looking, seriously. Just letting my 6yo start using a PC and it actually blocks typos to adult sytes that I know as well as direct blocks. its great
  • (2022-05-10) Stan The man: Hello, I'm a User of A9 And it works Great! But I'm having a problem with the Force safe search on? I'm on the Opera Browser and I think the Force safe Search option does not Support my Software. Could You guys maybe try to Update a9? I'm not sure If this is on my Side or a9 Is out of date. Thanks!
  • (2022-05-03) Carolina Derg: Really helps me enforce my rules on all computers under my management.
  • (2022-04-27) The Dragon Loving Lion: I wish the "Force YouTube restricted mode" worked better but overall this works okay.
  • (2022-04-25) VAE VIXIS: Honestly many people such as myself are Having a Problem to where Even if Most of Porn sites are blocked, Users like me still have access to Nudity on the Google Images. Is it possible in advanced setting you can put " Force images off. " Thanks !
  • (2022-03-14) Hormone: literally perfect
  • (2021-12-28) cameron novak: I don't know why everyone is saying this is a great extension when you can just go to your settings and turn it off without a password. could have been good
  • (2021-10-27) Bob: Does not work. Very easy to override questions asked by nefarious sites as to age and allows anyone to enter without blocking anything.Maybe a paid version of a different one would but Not this one.!
  • (2021-07-31) גילי מור: לא מסנן אתרים כאשר פותחים חלון גלישה בסתר.
  • (2021-07-29) Asif Rahat: Best one
  • (2021-07-23) Rounak: works pretty well till now to be honest :) kudos to the devs for their hardwork ❤🙏🙏🙏👍😊
  • (2021-07-20) Jamie K: Thank you for this program! It's the best chrome web filter out there. I will tell everyone I know about this. May God richly bless you and guide you.
  • (2021-06-15) Sayan Ghosh: It's an amazing experience while using this web protection. It not only blocks explicit results in Chrome but also protects PC from malwares, phishing etc.
  • (2021-05-31) Honestly, I'm a kid myself and I downloaded this for myself because most of the things I see on google images or things like that are disgusting, also always tell your kid to never search up "xxx" its porn. Anyways, this extension. I ABSOLUTELY LOVE IT. I've been searching for these all day and I finally found a good 5-star parental control extension! I blocked omegle and pornhub for myself and it really helped! This is a great extension and It's honestly #1 best free parental control extensions!
  • (2021-05-11) Le Vuong: Great. Blocks, warns me. Hope my child does not get angry.
  • (2021-05-03) Jose I. Vázquez Robles: Not bad, however, it can be easily uninstalled or inactivated by the kids from the chrome extension settings panel without required password. Or am I missing something? That would rate this up to the five stars level for sure!
  • (2021-04-29) MichaelLinda YangKuo: Best one so far.
  • (2021-04-21) Eitan: The best alternative for K9 web protection RIP!
  • (2021-03-24) Thad Litz: Works as advertised
  • (2021-03-23) Jim Ahlander: I just tried 14 parental control extensions from the Chrome web store (no joke), and this is literally the only one (so far) that blocked porn sites well. Some blocked a couple, but with this one, I couldn't find any that it didn't block. I'm sure there is one, but if its that hard, you get a 5 star rating from me. You do have to sign in with your Google account, but after that it works flawlessly.
  • (2021-03-04) សេង សេដ្ឋា: Best protection extensions for un-wanted webpage and imagery online. Absolute, love it.
  • (2020-12-07) John Ahlander: Works great as parental controls. Typo protection is pretty cool. Love the icons on searches.
  • (2020-12-07) Flint Stone: one of the BEST so far but some extra FEATURES would be very much appreciated..: -whenever a site is blocked with adult content a notification should be sent to an accountability partner's email set by the user -custom block screen maybe with a picture/text set from the user (-maybe an alarm sound as well) -redirect the blocked page to a url defined by the user
  • (2020-09-02) Tyler Wood: Super easy to use and install! Seems to work flawless so far!
  • (2020-08-27) Scott Robinson: In today's world, finding a tool as effective and easy-to-use as this is a relief. This is a great tool in my arsenal of protecting my family. Love it
  • (2020-08-27) Amy A: Needed this protection for my kids

  • (2023-01-15, v:1.0.3) J _Statt: Firefox release?
    Been using this on my older browser but decided to switch to Firefox recently, are there any plans on releasing this for Firefox?
  • (2022-08-04, v:1.0.3) Luke Montemarano: (one issue)
    So, only issue I see is that you can easily sign in as a guest on chrome which eliminates all extensions so you can circumvent the extension that way. Thoughts?

    Hello. You have the best filter on the Chrome store. A feature that one other filter has (though it does not work consistently which is why I uninstalled it) is the ability to block sites without a password. Would that be possible with A9? Thanks.
  • (2021-05-12, v: Katie Winkelman: Trying to install on child account
    I’m setting up a new Chromebook for my 9 year old. I’m trying to add this extension to his chrome browser under his account. When I add it, a box pops up that says “Creat Your Free Account” and there is a red button that says “Login with Google”. When I click that under my own account, I am able to add the extension perfectly. However when I am logged into my child’s account and click that, I’m receiving an Authorization Error - Error 403 access_denied. I’m not sure how to proceed here and any help would be greatly appreciated.
  • (2021-04-24, v:1.0.1) Derek Enz: Lock extension
    Hello Is there anyway to lock or password protect the extension from being easily removed? Thanks Derek
  • (2021-04-23, v:1.0.1) Samuel Krusiewicz: A few issues...
    For one, great job on making the best porn blocker available for chrome! I definitely enjoy many of the features you never see on any other blockers! A few issues, though...One, when typing in "porn", I do not get porn, but things like "best porn actresses of ___." The icon beside it is a blue, which means it is 1 of 10 on the content scale...This is bad. I entered the website, and of course did not get porn, but some dirty images, and films with explicit names. Other websites around it didn't have porn either, but all of them were not on the level of restriction that I had placed, which was ultra strict...OOF. Also, I REALLY NEED there to be no way to delete this extension...I do love that you email my partner if I delete it, but if I went rogue one day I wouldn't care what they'd say! This needs to be password protected! One question, though...Can't I use my Google account to sign into this service, just like my partner did, to bypass him? >>>BUT, if you are reading this and are now doubting this service, just remember that it is without a doubt the best porn blocker available for chrome that is free...If you want a great paid version THAT IS STILL AVAILABLE FOR CHROME, you go to: https://everaccountable.com/https://everaccountable.com/ Otherwise, good job and keep saving peoples futures!
