## What is uBlock Origin Lite?

uBO Lite (uBOL) is a reliable and efficient content blocker.

The default ruleset corresponds to uBlock Origin's default filterset:

- uBlock Origin's built-in filter lists
- EasyList
- EasyPrivacy
- Peter Lowe’s Ad and tracking server list

You can enable more rulesets by visiting the options page -- click the _Cogs_ icon in the popup panel.

uBOL is entirely declarative, meaning there is no need for a permanent uBOL process for the filtering to occur, and CSS/JS injection-based content filtering is performed reliably by the browser itself rather than by the extension. This means that uBOL itself does not consume CPU/memory resources while content blocking is ongoing -- uBOL's service worker process is required _only_ when you interact with the popup panel or the option pages.

### 5/5 — Le top du top

*2026-08-25*

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

### 4/5 — Great!!!

*2026-08-22*

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

### 1/5 — Doesn't support Safari 18.5

*2026-08-22*

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

### 5/5 — Best adblocker I’ve used on safari

*2026-08-16, version 2026.812.1211*

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.

### 5/5 — 最強の広告ブロッカー

*2026-08-15*

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。

### 5/5 — The Best of the Best!

*2026-08-13, version 2026.812.1211*

and free!

### 5/5 — Add pause

*2026-08-13, version 2026.812.1211*

Add pause With timer 5,15, 30, 60mins or whatever a few disable timers for a short time

### 1/5 — Causes Absurd Lag

*2026-08-12, version 2026.812.1211*

I’ve used regular ublock origin before without any issues but for the last few months this version has been causing insane lag/been literally unusable. Needs sorted badly. Do not recommend me basic troubleshooting. I’ve tried it. Ublock Lite is the problem.

### 5/5 — Mandatory

*2026-08-11, version 2026.804.1652*

Needed to use the internet now. Thank you for what you do.

### 5/5 — easy, effective, essential

*2026-08-11*

downloaded it first on my windows laptop and it changed my life. when safari extensions were added, this is the first place i looked. set it up once and all ads are GONE. i dont know how i ever used the internet without this. oh, and its FREE. download this and change your life for the better, 11/10.
