Sehr nützliches Addon! Rated 5 out of 5 stars

Hervorragendes Tool!
Blockt zuverlässig den ganzen Spamschrott im Netz, manchmal zuviel, aber sicher ist sicher! Ich habe ihn zusammen mit Bluhell - Addon laufen, da beide sich perfekt ergänzen und sich nicht in die Quere kommen. Was der eine hin und wieder mal durchläßt, blockt der andere dafür gründlich. Speicherverbrauch ist minimal, so das Firefox optimal geschützt ist. Das Monitoring ist cool - schon sehr interessant, was da so alles unsichtbar an Scripte und Werbung im Hintergrund ablaufen und geblockt wird.

Works exactly the way it says it does. Rated 5 out of 5 stars

I've started using this again, and I'm leaving another review to point out that the add-on works perfectly, and that the one-star reviews are being left soley by people who don't RTFM. On the other hand, I can't seem to point the sync field to a local file using the file:// scheme... is this not possible?

(Also, contrary to a recent review, enabling/disabling on the fly works just fine.)

More problems. Rated 1 out of 5 stars

Also, this blocks videos, not just prevention of autoplay. And Karma Blocker doesn't allow Disqus to work.

This ad-blocker uses least memory and quite different than all others. Great!

I just tested on MoneyControl.com and it is working Rated 4 out of 5 stars

I just tested on MoneyControl.com and it is working without doing anything. I need not learn anything new. Will check later how I can improve it.

Karma Blocker blocks a lot of unwanted stuff and ads right from the beginning without needind to tweat anything. In my opinion it is better than ad blockers because Karma Blocker does not let the element charge, so the blocking is faster and uses almost none resources.

HULU discovered you Rated 4 out of 5 stars

Works great. Trouble is that "HULU" has discovered its presence and now blocks its use. Have to disable to use HULU then reactivate when I'm finished.

I got tired of whitelisting individual domains with other extensions. This saves a lot of time detecting the common cases.

Thanks for the long-awaited update/fix! I was just about to switch to a different plugin...good thing I didn't have to because Karma Blocker is the best.

Cud have been a good addon but lack of easily available documentation and lack of author responsivenes plus trouble it creates with Yahoo and Youtube makes it too difficult for use.

May be good for you Rated 2 out of 5 stars

I installed this to stop ads, which it did admirably ... however ... it also stopped half the functionality of the Ebay auction site, which I use quite a lot. As a result it only gets 2 stars from me .. just a bit over-zealous :)

Would be great except for Yahoo email issues Rated 1 out of 5 stars

I have found out from experience that Karma does NOT like Yahoo email system. Your check boxes next to emails disappear, and the Delete, Move, Spam and Actions toolbar is gone. I disable Karma and Yahoo email works fine. I have also read through reviews and see I am not the only one with this problem.
