Causes huge Firefox slow down Rated 2 out of 5 stars

I'm on an Intel Core i7 4790 with 16GB of RAM, so resources shouldn't be an issue. Each time I click the Ghostery button to do anything with it, it causes massive hanging within Firefox - this is for signing in, for clicking 'trust site'. CPU usage increases from around 3% to 14-16% and makes Firefox unusable for almost 20 seconds. On the verge of uninstalling this. It's not a new problem, but to memory I'm quite certain it's been a problem for most of this year, if not before (I've just finally gotten fedup of it lol).

Evolved in to a thread consuming peace of garbage Rated 1 out of 5 stars

It used to be a decent add-on, but it seemed to be evolved to a peace of shit.
FF gets slow, and with every update the crap wizard to skip freezes the browser

Major slowdown Rated 1 out of 5 stars

It used to be good but... it was before.
Now the addon is slowing down so much firefox that it is completely unusable !!!

Verlangsamt alles nur noch mehr Rated 1 out of 5 stars

"Langsames Internet nervt? - Probier doch mal Ghostery" Von wegen!
Auf unzähligen Seiten friert firefox erst mal für ~5 Sekunden ein bevor sich irgendetwas tut. So ist es noch langsamer als mit den Trackern...

5 Stars Rated 5 out of 5 stars

The reason I am giving 5 stars is that with Ghostery you don't have to figure out which things you need to allow in order for media to play. All the work is done for you. Great job guys!

Causes slowdowns Rated 1 out of 5 stars

Started recently causing severe slowdowns when I had many tabs open. Renders this add-on unusable.

Is this really the problem? I have loved Ghostery! Rated 2 out of 5 stars

If the other recent reviews are true, I've finally figured out what has been making my browser SOooooo sluggish...
It's just recently, and it may have coincided with the updated Ghostery plugin as suggested by others.
I paused Ghostery, and the browser was much more responsive again.
Dang!
Please Ghostery, fix this quickly -
we need you!

From best at worst! Rated 2 out of 5 stars

So long ago (the previous version) ghostery was one of the best addons present. But then it turned into a slow and nasty troll that slowed down the fire fox so much that it would bounce it. Will our favorite ghost get back to us and make the fox go fast again? We will know in the next versions ...

Cuases significant slowdowns and lock ups on my system Rated 1 out of 5 stars

Immediately after installing this plugin I noticed a significant slowdown when using my browser and also had frequent lockups. I decided to stop using it. Instead I'm using 3rd party plugins for uBlock Origin. I know this plugin probably has extra features, compared to that, but it's not usable in my opinion. I have a very modern system as well, so I'm really not sure how anyone uses this.

Working but too heavy on the hardware Rated 3 out of 5 stars

I'm using high-end PC but still Firefox is much slower when running with this addon. Have to look for alternative.

Version 7.2.2 no longer working Rated 1 out of 5 stars

When right clicking on the ghostery icon I get a blank screen even when ghostery say there are 13 findings

Very slow! Rated 1 out of 5 stars

Firefox is very very slow now, after some recent udpate. Looking for alternatives I found out it is not open-source either, so you have no idea what they are doing with your data. Switched to open-source one (https://prism-break.org/en/subcategories/gnu-linux-web-browser-addons/)

Très efficace sur mon ordinateur.

Slow browser Rated 1 out of 5 stars

I used it for a long time, but for some time (1-2 month) the FireFox slowed down. Roughly. Shutdown is all right. I'm sorry.

Wouldn't be without it !!! Rated 5 out of 5 stars

Some users giving this low rating must have low IQ's. Maybe they haven't let go of their Mommy's hand yet. Just refreshed FireFox & it's the 1st add-on back on. I don't do it without protection. ;-|

It's too boring ! Rated 1 out of 5 stars

Bloque les redirections (ce n’est pas son travail)
On peut lui dire de faire confiance à un site mais ça ne change rien.
C’est trop chiant !

Blocks redirects (this is not his job)
We can tell him to trust a site but it does not change anything.
It's too boring !

Rated 1 out of 5 stars

I can't verify if this works, because nothing of this add-on appears in the UI anywhere ever.

/edit
It blocks absolutely fuckall.
