First off I am giving Adblock Plus 5 stars based on all the builds of it PRIOR to the new dev build based on the Chrome extension, all the classic Firefox builds of it are awesome especially using the Element Hiding Helper, which I use all the time. Please incorporate that functionality into the new extension based on the Chrome one! Also import/export functionality of all of the Adblock Plus filter lists and custom filters is essential too, we must not lose that feature! Anyway, there is a worse problem, when I use the new dev build based on the Chrome extension I do not see anything on web pages at all, it completely blocks everything and I have to disable the extension, a really serious bug. I would give the new dev build based on the Chrome extension LESS than one star because it is so bad, but the original extension gets 5 stars and my star rating is for the current stable version which is awesome. It sucks Mozilla is cutting off support for classic extensions and forcing this to happen!
DOES NOT WORK! This still lets ads through, if the ad companies pay them to whitelist their ads. This is not an adblocker and should not be called one, since it can't even do the 1 thing it is supposed to do.
The BEST ad blocker anywhere! Effectively blocks ALL ads and gives the option to unblock on sites that have pop-up requests that you need to deal with. It displays the number of ads being blocked unobtrusively next to its icon. An extremely well designed and implemented application
