I tried many add blocker apps. So far, AdBlocker Ultimate is the best.

I've been using this adblocker for a long time now and primarily to block adds on YT. It's been very effective at doing so with no problems. Only the occasional site will ask me to disable so as to remove annoying blockers that would otherwise prevent me continuing browsing their site which isn't a real problem. Update...It seems that YouTube are blocking videos as they detect my adblocker but when I disable, nothing changes and videos are still blocked. Have reported issue and given a screen shot and now awaiting outcome.

Even Blocks adds on YouTube Videos! Amazing!

Best ad blocker of all time

It's amazing, it even blocks YouTubes ads. xD

the newest update of 16 november 2023, since this update my pc uses 99.98% of the 16gb of ram, it ramps up till it uses just about all ram, as soon as you disable AdBlocker Ultimate in firefox/mozilla, it instantly drops off and the ram sits back to its normal amount usage between 2 to 4gb, i have had this same problem by the same adblocker twice before, not good when it hogs the ram and nothing has been done to fix it
