Läuft nicht mehr wirklich. Viele Werbungen werden nicht mehr geblockt, dazu wird nun trotz abschalten, die Anzahl der blockierten immer wieder angezeigt. Startseite zeigt kommt nun auch immer mit einem Fehler an.

Перестал работать везде

It stopped working a few days ago and I get ads everywhere now.

Why has it suddenly stopped blocking ads? After years of working well. I have no intention of ever buying anything based on ads - I do my own research and then decide - so this has been a godsend. But now, it seems to have no effect on ads, and I can hardly use the ad-littered sites.

Still selling their and your souls ("Acceptable Ads"). Use uBlock Origin for a non-commercial alternative.

перестало работать, настройки слетают

Used to work well. Now no longer works at all.

Seit mehreren Wochen werde ich von störenden Werbeanzeigen geplagt. Als ich mich dann letzte Woche zum Arzt begeben hatte, diagnostizierte er mir Augenkrebs. Vielen Dank Adblock Plus, dass sie mir solches Unheil zugefügten haben. Ich werde umgehend rechtliche Schritte gegen sie einleiten und mich auf meine Grundrechte berufen und um sie wegen schwerer Körperverletzungen anzuzeigen!
Sie hören von meinem Anwalt...

If you spent a lot of time and it remains VERY less than the old version 2.9. It does not even show what it says block! It's sad an extension that one day was the best and with only 1 update it became the worst of all existing!

As of TODAY it continues without displaying what has been blocked! This new version does not have even 0.01% of what existed in the old version! In other words, this version is absolutely useless compared to other Adblocks in the market like uBlock, uBlock Origin, and any other existing one is better TODAY than Adblock Plus. I do not understand how you are not ashamed to have been the Best in the World and TODAY to occupy the WORST Position in the world! The only explanation I see for this is that the Company has sold itself for financial interests, which is a shame in the same way!

Missing import/export functionality (present in older versions!)! Copying and pasting rules exported from older version into text-box areas is counter-intuitive (some of elements like prefixes and suffixes must be manually removed!)! A separate text-box area for "Element Hiding Rules" is missing (it is joined/merged with "Custom Filter Rules" now).
It lets through far too many advertisements and "Adblock Warning and blocking" screens (even with "Adblock Warning Removal List" and "ABP filters" added and enabled) - so it doesn't really do what it is supposed to do!
Shame on you, Adblock Plus!
Edit:
I have abandoned you after many years together in favour of your rival uBlock Origin - their add-on is far more useful.

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.
