I have yet after years of use using Firefox ad blocker seen ad's popping up. Highly recommended. David

helpfull add-on ^^

Stopped working on most every site recently.

The best ad-blocker.

The plugin claims to block ads, but based on observations, it seems to primarily block unpaid ads while allowing advertisements from paying clients to pass through.

Over time, more and more paid ads appear, raising concerns about the plugin’s true purpose.

This practice could be seen as misleading and raises ethical questions!

This a second or third time for me with AdBlocker Ultimate. My main criticism is that it causes substantial delays to web sites while Firefox tries to connect with it.
