Quite heavy and allows too many ads by default. And yes, 3.0 version is a disaster.

Increases CPU usage to 60 to 90%

its a fucking nightmare...I want to install and all I get from you clowns is the damn run around

In English using translator:
Starting with version 3.0, the plug-in menu has changed (it became like on Chrome), the plug-in degraded, started to slow down, the "visual" tool for setting the blocking is actually text, without the ability to enable additional settings (then what's the meaning of it?).
So download the version of "Adblock Plus 2.9.1" from the history of the plug-in, download the "Element Hiding Helper (for Adblock Plus by Felix Dahlke)" add-on to it. In the compartment with this addition, the older version is getting better than the modern one.

На русском языке:
Начиная с версии 3.0 поменялось меню плагина (стал как на Chrome), плагин деградировал, начал тормозить, "визуальный" инструмент для настройки блокирования на самом деле текстовый, без возможности включить дополнительные настройки (тогда какой в нём смысл???).
По этому скачивайте из истории плагина версию "Adblock Plus 2.9.1", к нему скачивайте дополнение "Element Hiding Helper (for Adblock Plus by Felix Dahlke)". В купе с этим дополнением, более старая версия становится лучше, чем современная.

AdBlock Plus doesn't block anymore. I used to this to block ALL ads now you developers are allowing ads to ruin my internet surfing.

Why on earth is it blocking pages that I am opening myself??? If a tab or window gets open's from a user specifically clicking on it to open it, then it should not be blocking it!! Flippen stupid. Nakes this useless!!!

C'est de la merde. Je n'ai que des problemes avec query bench

ABP was not responding to "disable for this site" instructions. It shows disabled but a weekly grocery ad that I want to see will not show up. I get a "fix your blocker or turn of private browsing" message. I tried disabling ABP totally. No change. I deleted ABP totally. Restarted Firefox. No change.

I have, to my knowledge, no other ad blocking enabled or installed.

This may work for other people and maybe for other stores, but not for me.

They sold out.. became greedy, lost the original mission

uBlock origin ist VIEL besser

It doesn't do what it is supposed to do. It turns off page content. Now I can't get the information I want.

I have use Adblock free for many years now (in the beginning it was all truly free but open for donations) and it get more and more tricky to use for every update especially the last cobble of years. The power to fight add's are going down hill or it get harder made it do what it did automaticity before.
And NOW !!!
Every webpage is now full of add's and it take forever to get rid of them all. Longer time than reading the page.
What good is it for then? Just asking.
Wish I haven't update the last 2 or 3 times.
A few month ago I had both Adblock and Adblock Plus and they "kill" the best part and the rest by only by a few "click". Now Adblock is gone.

No good for me any more.

Maybe it's sold to some "money-men" or what-ever. Anyway the spirit is gone

I tried writing many reviews years ago. The Mozilla people where biased against me and delete my reviews. I did nothing wrong and just pointed out the facts. They let the developers delete my reviews multiple times.

I will try again without saying too much because they will delete me again. Just please do some research into the company behind this. They are into so much shady business when you go down that rabbit hole. This "Adblocker" actually is payed by advertisers. They let advertisers buy themselves onto a whitelist, years ago they claimed its all community decision. Later it came out they where already getting payed by Google big time. Then even later they came out public-ally admitting it because there was no coming back.

Look into what the CEO of this company was into because doing this. This plugin had a "link correction" "feature". And guess what it did, it added reflinks to your amazon links to make them money. They later removed that "feature" after getting called out for it.

They should not even be allowed on here, but instead Mozilla features this addon. Do yourself a favor and use uBlock Origin instead. It not only had a actually ethical guy who AFAIK not even wants donations, its actually technically far superior, is faster!, uses the very same filter lists, has better default lists enabled, better list of choices, better UI and most importantly does not have a white-list at all. A ad-blocker with a payed white-list is a oxymoron in its own but again please research them its so crazy I did not even scratch the surface.

Adblock Plus v3+ for Firefox is a complete failure. You removed the two options I used most:
1. Turn off Adblock everywhere
2. Turn off Adblock on this page only

There HAS to be a way to unblock a page temporarily without whitelisting.

Everybody hates version 3, the complete rewrite is a total fail. It used to be a technical tool that advanced users loved, not it's a dumbed-down phone app style piece of junk. You should have just made the necessary minimal changes to work with the new add-ons. Maybe came up with Adblock for Dummies completely separate from the real deal. I'm on Firefox ESR 52, and may just have to freeze in time so that I can stick with Adblock Plus 2.9 Firefox is going the wrong way, too. Nobody can leave well enough alone.
