caused problems Rated 1 out of 5 stars

had to force quit Firefox every time I used it after installing this, at one point I couldnt even force quit Firefox, I had to force restart my computer, after I uninstalled this extension, everything went back to normal. I would touch it again with a ten foot pole.

Clueless users; superb addon Rated 4 out of 5 stars

This works beautifully, if only people weren't so ignorant and actually read the description!

This addon isn't full of "trojan cookies" or "malware", etc, instead as usual, it's users being utterly clueless and not reading the addon description.

Yes, it places hundreds of opt-out cookies to signal to various advert companies to not track you.
If you don't want this feature, like me, simply go to addon options or the addon icon, click on 'opt-out cookies' section and select none.

Instead, I have selected 'all' from the 'tracker block' section, which blocks all advert companies from placing tracking cookies.

Furthermore, it also allows you to delete HTML5 storage, which can also be used to place id's, just like cookies.
And from the 'Do Not Track' option, you can set it to clear all Flash cookies on browser exit.

Others have also complained about perf issues, which I've never suffered from, and I have this addon installed on at least 4 machines and several firefox profiles. However, for me, ghostery and adblock plus have a profound impact on memory usage as well as browsing performance.

Although a superb addon, it's now in desperate need of an update, as new ad companies keep popping up, which this blocker won't recognise.

!BEWARE! Trojan Horse full of Cookies! Rated 1 out of 5 stars

Not only does this add-on NOT work as advertised, it is full of hundreds of cookies that cannot be deleted until you uninstall the add-on!
Did any of the reviewers with more than one star even look at their cookies? Or did you assume they are all gone? Better check again, this add-on loads you up with more cookies than you imagined existed.
** !BEWARE! This is MALWARE!**

impossible to work with Rated 1 out of 5 stars

Revealing its effectiveness in making websites useless and not providing any help on how to solve it is quite a disappointing experience. The only link is to a plugin from avg....

If not trackerblock is designed to help the webabusers to live on and bake there cookies...

otherwise a whatcouldbe an excellent plugin has been hijacked..

don't use it ! Rated 1 out of 5 stars

firefox is blocked

linux mageia x64

Absolutely useless tool!!!! Rated 1 out of 5 stars

Blocked whole firefox from starting up again. If you look into the processes tool, you see it 's counting up the memory (I stopped it when reached over 2 GB) nothing else happens. stopping the process and restarting FF doesn't help.
Only solution to get rid of it, deinstall FF, reinstall it again and you will be prompted to the safe browsing mode (as FF was not started or shut in the correct way). From the Add-On-page you can remove it again. close FF and restart again and you get FF back working.

Tried on Win7 + FF 36.0.1, so not a Linux issue ... maybe it works only on Win XP?

Warning : Do not install this addon if you want to use Firefox.

I installed it and not it won't start.I've rebooted PC sever times, used CCleaner to clear data, tried to open FF in safe mod but it doesn't even open in Safe Mode.

Thanks AVG for screwing up my computer.I don't understand why Mozilla hasn't removed this addon from library yet.It seems like AVG stopped supporting it long time ago anyway.

Didn't work. Firefox wouldn't start up.
To start in safemode:
Click on Start > Run

Type the following command: firefox -safe-mode

Once in safemode, the addon is called Privacy Choice Tracker Block. Remove it, and FF will start right up.

broken Rated 1 out of 5 stars

firefox won't launch with this enabled.

Must safemode, remove plugin, then it works. 0/10, looks great though on the screenshots

Warning, do not use! Rated 1 out of 5 stars

I cannot understand why this add-on is not going to be removed after that so many people report about how the add-on crashed their Firefox/System??

I installed it (I was missing to read the comments here before...) on a fresh (!) and new installation of Ubuntu 14.04 and afterwards Firefox was not able to start anymore, just left me with a blank screen. Even after restarts of the system.
I was just able to fix it by reinstalling Firefox multiple times afterwards and finally reset Firefox to its factory settings (without all add-ons etc).

Do not use it! It will most probably crash your system, too. Just like so many other people report in their reviews. (see below)

Rated 3 out of 5 stars

The comments suggest that this is a bad addon. Had no problem thou, but fear for my browser stability!

TRASH!!! DO NOT INSTALL IT Rated 1 out of 5 stars

This addon does not allow to start FF. Memory usage rocketed from usual 350 Mb up to 2,7 Gb.

Фуфло! Грузит память в 10 раз больше обычного и не даёт запуститься Фаерфоксу. Не устанавливайте, не теряйте время!

Rated 1 out of 5 stars

As with many previous reviewers, my FF refused to load correctly once this was installed. I tried it twice, with and without other addons present & same result each time.

Possible conflict now. Rated 2 out of 5 stars

This appears to conflict with (I think) a Ghostery update. Was installed with no problems but now 100% processor usage and machine locked up so badly, had to use power button several times to shut down. Started FF in safe mode and gradually found out which add-on was the problem by trial and error. Disabled at present.

FF will not start again after this addon Rated 1 out of 5 stars

After installing this in my FF v24 on Windows7 and restarting, FF would never start again (in normal mode). I had to start in safe mode, disable this addon and start again. I really want to use this type of addon but this one is no good to me.

Rated 2 out of 5 stars

Major conflict with 'Ghostery' add-on. Causes memory leak type issues. After installing 'TrackerBlock' FF DOES NOT LOAD and cycles through memory.

********************************** PLEASE update this much loved and utilized program!No other solution shined and just worked like TrakerBlock. :)

Made browsing P-A-I-N-F-U-L-L-Y slow Rated 1 out of 5 stars

It was taking at LEAST, and I mean at LEAST, 30 seconds to fully load pages. Sometime I would see the portion of the page in my viewing window load but I would have to wait another 15 seconds for the ball to stop spinning. Then when I tried to scroll down, the ball would spin again for a long time and it would become apparent that the rest of the page (beyond what was in initial viewing window) had not loaded at all. So basically, the ball would spin frequently when I clicked on links or tried to scroll down. I knew it was an add-on that was making my computer slow because my browsing was fast before and then after adding a couple add-ons browsing was like wading through mud--I just was not getting anywhere. Luckily, I realized it was this add-on giving me the problem because I like the other two add-ons I have. The slowness of the browsing with this add-on was so bad that I made it a point to create an account on this site just so I could write a review and warn other people and let them know that if their computer is really slow it's probably because of THIS add-on. Did I mention it was tortuously slow? It was so slow I would get up and do stuff while I waited for pages to load. I haven't dealt with a browsing experience that slow since a couple years ago when I tried browsing on an old computer that I bought in 2001. That old computer has since been discarded because the browsing speed was so slow. If I hadn't figured out that this add-on was the culprit of the slow browsing, I may have thrown away this computer as well and it's only a couple years old.

Good, but in my FF interferes with HTTPS Everywhere 3.x/4.x

Massive performance problems Rated 1 out of 5 stars

Found this addon to be the culprit of massive performance problems with Firefox, slowing Firefox startup a LOT, causing freezing every time loading Twitter and generally slowing browsing down.

Going to check Ghostery out if theres less problems with it.
