It does a great job hiding ads without slowing down your browser.

Big thanks for this add-on, I was really fed up of the constant FB ads !
It's working fine on FF 77.0.1.

EDIT October 2023:
It seems the addon crash when looking pictures or something like that, and then it doesn't block anything anymore. I have to disable it & enable it back to make it work again.

One of the best extensions for Facebook. Thanks Z.

This is an important and effective extension for anyone who has a stature that should be protected, or who otherwise recognizes the seriousness of security from third-party exploitation. The breadth of ubiquity of FB interfaces makes this valuable for everyone who browses the Web--not just FB users. Most FF users understand the importance of security, and this extension effectively supports that objective. Inherently, any type of security will always cause some inconveniences of legitimacy, and if some occasional complications are unacceptable, either browser security isn't for you, or you should consider being among those who help to refine open-source software like this--which volunteers allow for others to analyze to demonstrate the integrity of the security. It excellently complements other anti-tracking/security software, with FB-specific protections, but without needlessly broad permissions or common conflicts; this is superlatively well-targeted security.

Has zero effect in Firefox 75!! useless

Removes the ads after they load which means the very first one at the top of the feed shows up for a second but as you scroll down normally you won't see any more ads. I'm happy with that.

Does what it says it does, as far as I can tell :)

it works. thank you.

Awesome. As soon as I installed, sponsored post disappeared without the need to refresh. Hey FB, FU!

Awesome, I have this on Firefox and Chrome.

Still had video ads, at least it got rid of a lot of other ads nicely.
Instead of(or in addition to) facebooktracking you, now...
"Access your data for mgziminsky.gitlab.io"

Please add a button on the add-on's page in about:addons to clean already saved bookmarks, too. :)

Brilliant. Your extension saved me from having to write my own - did exactly what I wanted. Bravo!

Efectivamente, te permite esconder o remover anuncios y otras cosas molestas de facebook, aunque se podria mejorar su velocidad de funcionamiento, es la mejor opción, recomendado. :D

I don't use this extension, but when I was looking for a Custom CSS extension, I saw this one listed with the unique icon, which immediately made me LOL.

So, in tribute to making my day, because of the icon of course, I posted this 5 star review.

I don't know if your extension is good, but your icon was excellent!!

Semble faire le job. Nickel !
