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.

*finally* a default list, but also needs a subscription feature like adblock plus Rated 4 out of 5 stars

much like adblock plus this extension has the potential to serve those who never craft many of their own respective rules. with a subscription feature this extension will enable those philanthropist techies to facilitate ad CRUSHING power for the rest of us who HATE the privacy violations of ads

Just the most essential FF add-on for me… Rated 5 out of 5 stars

Karma Blocker is just the most essential FF add-on for me – I use it since 3 years. Surfing the web is so much faster with it since with Karma Blocker you can filter out nearly all that ad and other crap. Thanks sooo much Anthony !!

Having switched over from Adblock Plus I have to say this addon is pretty unobtrusive. I haven't had to tweak anything really except the aforementioned Yahoo Mail and added a rule for zillowstatic.com when I was browsing there once but all in all it's not caused me any problems. I prefer this a lot over adblock plus simply because it doesn't really need to queue up a black/white list of much so it ideally doesn't need much updating nor overhead on the browser.

This breaks yahoo mail unless you know how to make changes to the rules to not break it. Those changes are not identified. Here is my interaction with the developer on this:

My bug report:
FF 6.0 on Win7 64bit. I swapped out ABP for Karma. Then I noticed that my yahoo mail did not work correctly. I am on the new version of yahoo mail. There are checkboxes to the left of each message in a folder. I can no longer check the box. If I click on the box the message is opened. It should just check the box. I disabled Karma and tried again. It worked fine. :(

Please let me know when this is fixed. I really want to replace ABP.

His reply:

Working as intended. Tweak your rules.

Dupe of #511

My reply unanswered so far:

Thanks for the reference to ticket 511. I read it. Unfortunately it does not solve the problem. Can you give some hints has to what needs to be done to the rules to make karma blocker work with yahoo mail? It might be a good idea to have the standard ones that are supplied with karma blocker work with most major apps, which I think yahoo mail is one of them. Or at least provide more detailed documentation for users to fix the rules when a site is not working because of karma blocking.

Brilliant Anthony!
Thanks for sharing your talent.
What a tool, regardless it's new.
Even tough, there are some adds that dodge KB, overall in No-English websites, it blocks plenty of annoyances that Adblock & Element Hider cannot, so I preferred over them.
Would be handy a command in the context menu to block the dodgie ones, and a kind of panel to undo actions.
So far, this extension is the most innovative and effective in years. An example of its potential is that I uninstalled Adblock & Element Hider, which are a must for add haters.
Keep it going my friend, I will put an eye on its development.
Thank you.

This is the greatest ad-blocker I've seen yet. It's very effective and surfing is much faster and enjoyable without publicity.

It does however interfere with some features in facebook, youtube, etc.. But there is a little known trick that allows for easy enabling/disabling karma blocker on the fly.

* Right-click on the toolbar on top and click 'customize'. The customizing dialog will appear.

* Find the Karma Blocker icon in the dialog, Pick and slide it onto any toolbar.

* Close the dialog.

A simple click on the Karma blocker icon in the toolbar will enable/disable Karma Blocker. Works great !

great, but causes big problems with google maps Rated 4 out of 5 stars

I love this add-on. It worked totally as stated, with no problems, until I started using Firefox 4. At that point, Google Maps stopped working reliably at all; problems included not being able to zoom in, the page hanging at "loading" and my not being able to do anything. When I disable Karma Blocker, Google Maps goes back to normal. Anyhow, five stars for the ad blocking, with a deduction for problems with Google Maps.

This is Awesome! I'd tried ad blocker plus and noticed no difference. I was a little daunted by all the talk of having to know how to code your preferences but decided to give it a shot. I didn't have to do anything - I installed Karma Blocker and restarted and every single ad was gone. I'm in Heaven!!!!!

Good Rated 5 out of 5 stars

Good and fast adblocker, but I have some question. Does Karmar Blocker need restart Firefox to take effect after change Rules ? I change my rule for Hotmail, but seem it doesn't work, after restart Firefox, it works =.= I hope Karmar Blocker will have feature like AdBlock Plus, change rule without restart Firefox, what a nuisance, restart Firefox takes a lot of time and inefficient =.=

I'm using Firefox 4.0 Final, Karmar Blocker 0.4.4.

More info:
I've tested for Firefox 3.6.16 and Firefox 4.0 Final, Firefox 3.6.16 no need to restart but 4.0 must restart Firefox after edit Rules. Hope you will fix this problem soon. : )

This just the ticket for those new pop-ups that AdBlock Plus is missing.
After weeks of trying to stop these annoying things and getting AdBlock to only partially block some of them, installing Karma Blocker has killed them. Peace at last!

Karma Blocker is great Rated 5 out of 5 stars

Karma Blocker is once again, with FF4 compatibility, the ultimate crap blocker. Small, fast, configurable, fantastic.It is NOT for people who wont write their own blocking rules.

Thank you for this terrific addon. I've been using it for several months now and I'm very happy with it. Light and highly configurable - exactly how I like it.

Please update it for FF4.
