Does what it says on the tin...

Blocks almost all of the ads. If the websites develop a new scheme for placing ads AdBlocker Ultimate produces a counter scheme.

great

excellent as always.

AdBlocker Ultimate is working great with Firefox Browser. I have no complaints.

OK

I've been a faithful AdBlocker user for the last 25-ish years and will continue to use it long into the foreseeable future. The ONLY reason I am givig it 4/5 stars is lately it hasn't been stopping AdChoice ads from popping up in the middle of my Google_Chrome/Firefox window & blocking content from being viewed AND/OR stopping AdChoice tabs on the upper/lower right/left sides of my Firefox screen from changing content and slowing down my Internet. Would like to have a way to have AdBlocker completely stop AdChoice ads from even popping up

(EDITED): Changed my rating to 5/5 stars...Reason: A fellow Firefox user replied to a Reddit forum post and made aware to me of an option filter I overlooked in AdBlocker Plus(Pro)settings...Filters tab > "Fanboy's Annoyance List" toggle was gray (off).
