これは [広告をブロックする仕組みをブロックする仕組みをブロックする拡張機能] です｡ しかし､ 正常に動作しません｡ 具体例として､ 以下のメッセージが表示されます｡

なお､ Firefox には [広告をブロックする仕組みをブロックする仕組みをブロックする拡張機能] が 2つ存在します｡ [Anti-Adblock Blocker] と [Nano Defender for Firefox] です｡ 両方で上記のメッセージが表示されます｡ よって､ 全滅です｡

Nano Defender Integracion and filters are outdated because gitcdn.xyz its down an long time ago! Please update sources.
In alternative you can use mirrors to continue using Nano Defender. Google it

The extra instructions for uBlock Origin no longer apply as the filters listed for them are broken. This still hasn't been fixed after months and months, and the creator has seemingly disappeared from the internet judging by their github profile, so I've given up on this extension and its filter lists. I recommend people use the Fuck Fuckadblock filter list instead, it seems to do everything this extension and its filter lists used to do and more: https://github.com/bogachenko/fuckfuckadblock

Ars Technica says uninstall immediately!!! https://arstechnica.com/information-technology/2020/10/popular-chromium-ad-blockers-caught-stealing-user-data-and-accessing-accounts/

This extension is now gone. Look at arstechnica article below. UNINSTALL IT ASAP, THEY STEAL YOUR DATA!

doesn't work. Downloaded and followed the many steps that should have presumably gotten it working with uBlock and...nothing.
