1Blocker overview

1Blocker website inspector allows you to detect a number of ads and trackers on a page, analyze the content size and loading time, as well as estimate 1Blocker effect in Safari. See for yourself how many ad networks and analytics providers build deep profiles about you across the web.

Using 1Blocker you can also block these ads and tracking scripts in Safari. In addition to ad blocking, you can also block comments, various social widgets, share buttons, obtrusive EU cookie law notices, adult sites, and more.

I was just told that the server for 1Blocker is in St. Petersburg, Russia. I'm going to deactivate this extension unti l learn if this is true; if it is, I don't want any Russian software running on my Mac or any devices I have. Too bad, because I really liked it. But during this war, I can't take a chance that Russia would attempt to exploit the software we run to help them in their war on Ukriane. If what I was told is not true, I'd like to be told. Assuming it is true, you should all consider deactivating this software now.

Used to be 5 star. Seems to me things went haywire with Catalina. It stopped working very well and it caused all kinds of lockups etc. I switched to Adguard and haven't looked back.

1Blocker gets the job done. Cleans up the web in Safari. Easy whitelisting of sites. Element hiding. Works very well, doesn't slow down my browsing experience. Some people need to get over the subscription model, and not use that as a basis for bad reviews. This is a solid ad blocker for macOS.

I no longer use Safari on my Mac, I've moved on to Dissenter. Still use 1Blocker on my phone and still like it.

Seems to work reasonably well; though doesn't block what it claims to block. Easy to use and hasn't crashed for me - although there is a major bug which prevents the tabs from displaying properly. The biggest disadvantage is that 1Blocker appears to be completely unsupported: there's no easy way to contact the developers; emails sent to the 'personal' site of one of the developers are never unanswered. Perhaps the app is no longer in production?

Looks like I'm the only one here that hardly came across a crash or malfunction in the almost two years I've been using it. Plus, the developers are quite responsive and kind. My ad-blocking choice for Safari on both macOS and iOS.

Converting £9.99 to (US$13.75) is way too much when there are so many excellent yet free ad blockers. Could the developer reprise the former price of US$4.99? If not then I'll have to look elsewhere for an ad-blocker .

excellent at blocking ads but also causes several websites to not load properly. As a result, the links on an affected website do not work anymore. Very annoying as whitelisting a broken website does not fix the issue. Also, comments on websites are sometimes blocked even if you disabled those rules. Reporting an issue does not get it fixed.

It's no longer $4.99. It's $9.99. That's actually a bit too much for an ad blocker, in my opinion. I wish there were a trial version so i could know if it was worth it. I do love the iOS version.

With all the free ad blockers available, why would you not want to try this first to see if it was worth the money? If this blocker does not meet your needs, you would then have to hassle with Apple to get a refund.

Reputable, confident, developers do provide trial copies of their apps!

Comprehensive and fast ad blocking. I took a chance on this because the iOS version is so good. On Safari I used to use Ghostery, and then settled on uBlock for Safari and Chrome. Now I use 1Blocker in Safari, which seems a bit faster in operation than uBlock. Tweaking blocking to let in some things can be a bit more fiddly than with other options, but overall I'm very happy with 1Blocker. (FYI I still use uBlock on Chrome, and Chrome is my primary browser.)

It's great on iOS but cannot see too much blocking on my Mac I just left a comment that is not completely correct about what you can read in Safari prefs-Extensions "1Blocker Menu" can read, modify and transmit content from all webpages.This could include sensitive information like passwords, phone numbers, and credit cards. This is not by 1Blocker but it is in the new Safari 10 for any extensions. I just installed a second one and it says the same. I apologize and ask the moderator to cancel my previous comment. For this reason I give 3 stars and hope to see more blocking in a future update
