Despite my previous review, this is one of the best of all Add-ons, period. Rated 5 out of 5 stars
Lately this add-on has been receiving a lot of bad reviews because of their new 'Acceptable Ads' policy (information located here: https://adblockplus.org/en/acceptable-ads).
Though it is annoying and may be difficult for the novice user (which I imagine are many), this is, without doubt, the finest ad-blocking suite I have found to date. I have been using it for years, and can't imagine having to find a replacement. I am sure many of the recent bad reviews, including my own, have been based on this emotional response to the situation.
Obviously this setting can be changed rather easily. I would suggest to Wladimir he update his webpage to help users who may be ignorant of the recent changes, to help them undo the default subscription.
This add-on deserves unreservedly, a 5+, for it's usefulness, and previous ease of use. I am still in shock when I use a browser without AB+ to see how many ads there are, almost everywhere.
