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.

Ads/Promotions from it keep popping up and can't be turned off

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.

Works, but lately it feeds you a bunch of ads. Very disappointing, but I'll be moving on to some other solution because of it.

too much ads

It'd be hilarious if it weren't so aggravating: an ad-blocker that spams you with its own pop-ups. Whoever is managing Ghostery needs to go. Uninstalling.

Was great at first. In the past few months, every time I open my Firefox it pops up an ad for something or other.

ghostery has become what it is supposed to block. Keeps spamming it's own adverts in the form of popups. once good now useless bloatware trash. To Dev response: I did all that before making my review and it still popped up the special ghostery offer every single time I opened browser. The issue is now resolved by removing ghostery from my browser. Ghostery was redundant anyway since I run abp and don't have to deal with pop-up from them. I am also going to say that I highly doubt this has a legit 4.4 star rating and going to suggest that it only does due to click bots.

I don't care how good it works.
It showed me a popup today to checkout "today's deal".

Every time I start firefox it shows an unwanted popup.

Кусок говна! Постоянно вылазит справа сверху об их АХУИТЕЛЬНЫХ СКИДКАХ НА КАКОЕ ТО ГОВНО!! Окно программы СПЛОШНОЙ СПАМ на 100% в общем ХУИТА для долбоебов!!!

Popups for shopping at black friday. WTF? i especially don't expect that from a privacy add-on. uninstall directly.

Wanted a little bit more privacy on my browser, so tried this addon. Worked ok for a while, and was non-intrusive until recently, when it started to prompt me EVERY time I open my browser, to redeem a "coupon code" for some payed service I'm never going to use. I clicked "x" on 3 seperate occasions, it asked me today, and it got removed. ^_^ 3 strikes etc. Disabled "unlock rewards" in settings, and no other setting to disable spam/ads.
