you can't switch off "Ghostery Rewards", thus you got everywhere ads ... I removed this extension, sadly after years...

It was great. Now it's compromised, it allowed my search to be rerouted to a fake Firefox billionth search rewards scam site. Then didn't allow me to backtrack to my original search.

Clikz, or who-ever they are. They make money from your data. Ghostery has been completely subverted.
AVOID AT ALL COSTS.

It will give you interrupting ads itself. Pop ups from its "trusted partners" will occur and interrupt. Do you want to avoid ads? Do not download.

中国用户就别用了，直接把你的百度图片认成广告给屏蔽了，别的其它一些搞不好也能屏蔽了

This add on has worked for years all up until a week ago. Now it doesn't block ads anymore and offers you a premium subscription to ghostery to get more "protection". Ghostery have now put up a paywall in order to experience what users have been receiving for years before, Sad day for the internet

I have used this wonderful add on, on and off for years. Recently almost every time I open a tab, or go to a website up pops the advert for MIDNIGHT! I can't seem to turn this off. WHAT IF YOU ARE NOT INTERESTED IN THIS UPGRADE? Seems the team at Ghostery figure why not irritate people after all if they use the add on they are a captive audience. It is ashamed we can't elect NOT to be bothered with this annoying advert. ISN'T That apart of why we use this add on in the first place? Uninstalling. Deserves negative 50 stars just for this issue. I would not waste the time or bandwidth to download this add on any longer. They lie about blocking ads when it's their ad that is being pushed every few moments. In fact I think I will file a complaint with Firefox, the Google Play store as they purposely mislead consumers with the claim it blocks ads.

I've had Ghostery installed on Firefox for years now and it's served me well, but I just removed it & won't be back—Ghostery has become increasingly commercialized and with its latest update is repeatedly intruding with pop-up ads of its own trying to hock its monthly paid "premium" service. Ghostery's become an ad-blocker that—bewilderingly—shows you ads; moreover, there's no functionality it provides that other privacy add-ons don't/can't.

Do yourself a favor and skip clicking the install button & just close the tab.

Gibt vor, ein datenschutzorientierter Werbeblocker zu sein - und blendet dabei selbst penetrante Werbung ein - und das unter Mißachtung des Datenschutzes: So werden auf den Seiten von Onlineshops sehr extreme Einblendungen von Mitbewerbern gezeigt! Ganz übel! Dieser "Werbeblocker" ist meines Erachtens Betrug am Benutzer! VORSICHT!

This addon has its "Ghostery Rewards" function turned on by default, which basically sells your information to certain companies which the developers have "whitelisted."

此插件中的“Ghostery Rewards”功能默认是开启的，具体功能就是把用户的隐私信息发送给和开发者合作的特定公司。

Its not working

They no longer block all trackers, they now sell your "anonymized" data.

Disables blocking periodically, complete shit

Significantly affected performance after installing, for example I can't even smoothly switch between tabs using Ctrl+PageUp/PageDown when this addon is enabled.

Edit: I'm just looking for an addon that blocking JavaScript from certain sites, it seems this addon is overweight for me.

Just does not block ads or popups. Move along. Maybe the paid version lets you block things aggressively IDK
