The 1st addon that actually remove those pesky sponsored ads for me, the option to either completely remove make them collapsible is great too.

Just installed it, works fantastically so far. Ads, sponsored and suggested posts are collapsed, with the option to click to un-collapse them. (You can also make them hidden entirely in the extension settings.) Finally, the terrible website that I only reluctantly go on to find out what my acquaintances are up to will actually only show me what my acquaintances are up to.

It doesn't work anymore. Please, update it.

Please add removal of __cft__[0]= tracking data... example __cft__[0]=AZWAFYZG_rxiiC1QGzg2heuX0uoORIAmJOZaeZKgGZ1ozmtzFbHY57hkDfRXQD_qwawr7zCtAqnpbP6XhBJQ0MAQU-5JNRHZUayIshV-PVWEyFJTz4VKECw1OM36odLRBRE&__tn__=-UC%2CP-R

Works very well. Collapsing adverts and recommendations which normally appear every 5th post make facebook a different experience. Highly recommend.

As of December/2020, it does not block any ads, sponsored products neither facebook ads during videos.

It works in Firefox-84! Unlike two another ones - Ad Blocker for Facebook and AdBlocker for Facebook - last weeks both don't work anymore. Before login FB with new blocker you should clean cookies and cash in your Firefox.
P.S. It worked fine for two years. But it stopped working in October 2022. At first occasional ads, then massive. Good bye, Chinese toy! And thanks, though, for two years.

One of the best add-ons ever made.

Does what it says. It also work on Firefox for Android, despite no being marked as compatible

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.
