What's New in uBlock Origin Lite

2026.825.1619

August 26, 2026

- Replace List-KR with filterslists-KO - Add missing configuration items from backup/restore - Fix "Filter lists" rendering on reset/restore - Updated filter lists - Note: When the extension updates, allow for a few seconds before it is fully ready (the more rulesets enabled, the longer it takes). Safari needs to internally convert updated DNR rulesets into its native content blocking rules.

Le top du top

La référence open source. L’open source c’est le futur.

Great!!!

Ever since I updated to iOS 26.6, blocking has started taking longer to apply.
The app itself is great, though.

Doesn't support Safari 18.5

I can download this app but can't use it because it doesn't support Safari 18.5

Best adblocker I’ve used on safari

In my opinion it’s better than Adblock pro, ublock tends to play better with websites and not break them like Adblock pro sometimes does.

最強の広告ブロッカー

ついにiPhoneに来てくれてました。無料かつオープンソース(不正がない)の神アプリです。
ただしiPhone用でありiPhone自体が不便なので仕組みに限度がありますから、どうしても本来のPC版、またAndroid版より使い勝手が下がる印象、特に元々のv2仕様よりはブロックが弱いと思われます(これはAndroidでも同じですが)。

それでもiPhoneでこれが使えるのは素晴らしいことであり、iPhoneの中でも恐らく最強広告ブロッカーだと個人的に思います。

使い方:
・iPhone本体の「設定」でSafariから拡張機能のこれをオンにしてください。
iPhoneではSafariにセットするしかありません。iPhone自体が不便なので(大事なこと)

・地味に気付きづらいポイントで、ubrockに与える権限のポイントがあります。
拡張機能ページの下の方にある、アクセス権→「全てのwebサイト」これを「許可」に設定してください。
(※ソースコードが全て公開されている上に長年の有名アプリケーションなので不正はありえません。)
そこを「確認」などにしてるとメイン設定の「デフォルトのフィルタリングモード」が変更出来なくなります。
そしてこのモードは「最適」が一般的にはお勧めされます。
私は「完全」で使いますが、強くするほどページが正常に機能しづらくなるトレードオフです。

・その他はライトユーザーは気にすることはありません。
フィルターなどはわからなければそのままで問題ありません。

・拡張機能ページにある「ストレージを消去」について、ですが、ubrock内で設定したものが全てリセットされてしまいますのでご注意ください。
ただし、キャッシュも含まれるようなので、設定を戻せるのであればリフレッシュ用途で削除しても問題ありません。
