Be careful, read the terms of use, read the contract since it is a private company, so there is a service contract.

The contract indicates that private enterprise retrieves some of your data and resells the analysis of the data, or the behavior of Internet users.

If you look at the origin of this private enterprise, it is registered in the New York State Trade Register as an advertising company.

It is an advertising company that fights against its competition to dominate the market alone.

How is it that it is recommended, would there be no jurist at The Mozilla Foundation to read the contracts or check the registers of commerce ?

New York Trade Registry, see its true original name before Evidon.
Put Evidon, and its original name was : Adsafe (The Better Advertising Project).

For a while, it is recommended, even partnership, with something regarded as a sect in some European countries :
- The Church of Jesus Christ of the Latter-Day Saints

It was even recommended by multinationals !
- Unilever
- Nike
- Toyota
- Lenovo
- Johnson at Family Compagny
- JP Morgan Chase (subprime crisis - planetary bankruptcy, etc.)

Воровал приватные данные, не думаю что сейчас что то поменялось.

selling the data of your users? you traded ads for tracking by the ad-blocker. sounds like a lose to me.

nice gui, statistics, and lot of options, nice database, categorization, and frequently updated....just can't rate this better than worst because it contacts many servers in background without my knowledge and choice and option to turn it off, meaning even if I disable all additional options, so had to block them via hosts file (apps.ghostery.com, cdn.ghostery.com, collector-hpn.ghostery.net, api.ghostery.net, safe-browsing-quorum.privacy.ghostery.net, cdn2.ghostery.com, d.ghostery.com, cmp-cdn.ghostery.com)...looks like tracking

Жадное приложение

Behindert teilweise die normale Funktionalität von Webseiten (z.B. Mouse-Over-Menü oder Slider). Nicht zu empfehlen!

Used this for years. Not anymore. I don't want "acceptable ads", I don't want popups, I don't want "rewards", I don't want "anonymized" data collection, all I want is ad-blocking. And no, I don't want to "disable" harmful features myself, or accept being tracked by an ad-blocking software. It's a matter of trust. Trust, once lost, is never recovered. Just as it happened with AdBlock. Using uBlock origin now. Just ad-blocking, no ifs and buts

Loved it for years. Had to get rid of since it no longer is a privacy ad blocker. Too bad.

A "privacy ad blocker" that invades your privacy. Bruh. Using uBlock Origin from now on.

Add blocker with adds. No, thanks.

Annoying ads which can't be disabled, absolutely not lightweight. It can't even display the overloaded settings menu on older CPUs.

As others have said: was fine until recently when it started adding pop-ups of its own. Absurdly bad ad-blocker now.

It absolutely doesn't matter that this feature can be opted out of. I already tried to opt out of ads by installing the add-on in the first place. I'm now opting out of ghostery's ads by just uninstalling it. ublock origin does the job just fine as, I'm sure, do many other ad-blockers that don't stuff their own ads down your throat.

It was a friendly old ghost, but now it joined the dark side. The Rudy Giuliani of Firefox extensions..

Too much spam from this Extension

Suddenly began to show Black Friday ads some days ago. Do not trust this extension any more. Questionable business ethics. Uninstalling.

Ironically, this add on spams you with ads almost every single time you open your browser. Stick with uBlock Origin!

Worked great for me for several years, never had any issues until the last few months, just the occasional notification of an update.
Now every time I launch Firefox I get a pop up ad from the add-on for black Friday or something else I don't care about or want to see.
Cannot recommend installing in it's current state.

You were the chosen one! you were to destroy the ads not join them.

too much ads
