How to block porn in Chrome on iPhone (and other browsers)

Written by the developer of The Blocker. Facts checked 21 October 2026 against Apple’s documentation and the app itself (version 2.9). Menu names can differ with your iOS version and language.

Why your Safari blocker doesn’t work in Chrome

A content blocker is a list of rules that Safari applies before a page loads. The list belongs to Safari. Apple’s developer documentation says the Safari view some apps open (a Safari window inside the app, with a Done button) keeps Safari features “such as Reader, AutoFill, Fraudulent Website Warning, and content blocking” (Apple). Chrome, Firefox, Brave and DuckDuckGo are separate apps that don’t load Safari’s blockers, so a Safari blocker never sees what you open in them. That is how content blockers work, not a fault of one app, and it is why The Blocker Pro added Strong protection.

What Apple’s Screen Time filter covers

Limit Adult Websites lives in iOS: Settings › Screen Time › Content & Privacy Restrictions › App Store, Media, Web, & Games › Web Content on iOS 26 (Apple’s steps). What Apple itself says about its reach:

• “Apple devices can restrict Safari and third-party apps to specific websites.” The adult option limits “many adult websites”, not all (Apple).
• On iOS 27, website approval works in “Safari and other supported browser apps”, with no list of which apps (Apple).
• Browser makers get a Screen Time tool “to report web usage and block restricted webpages” (Apple’s developer documentation). Apple doesn’t publish which browsers use it.

So Apple built the filter to reach beyond Safari, but it doesn’t promise any particular browser. If it fails even in Safari, read Limit Adult Websites not working; for other ways around it, see Limit Adult Websites bypasses.

Where people report gaps

The best-known complaint is the Apple Community thread “Screen Time not blocking/affecting Chrome after iOs 14 update”, posted on 1 November 2020. It has 95 replies and on 21 October 2026 showed 1,328 “Me too” votes (the thread). To be fair about what it shows:

• It is old: iOS 14, closed, last replies from mid-2021.
• It is mostly about time limits. Chrome didn’t appear in Screen Time’s “Always Allowed” list; the top-ranked reply is a trick for App Limits (search for “Chrome – System”).
• Website reports disagree. One January 2021 reply said sites blocked in Screen Time still opened: “It does NOT work when using Google Chrome.” Another that month said Allowed Websites Only did work in Chrome.
• The usual fix was blunt: “uninstalling Chrome and blocking the App Store app.”

These are users, not Apple, and iOS has changed since. The lesson still holds: don’t assume Chrome follows your settings. Test it.

A two-minute test on your phone

1. Pick a harmless site you don’t need, such as a news site.
2. In Web Content, with Limit Adult Websites on, “tap Add Website below Never Allow” and add it.
3. Open it in Safari, then in Chrome or whichever browser you use.
4. If it opens in the other browser, that browser isn’t following your Screen Time filter. Remove the test site afterwards.

Fix 1 (free): make Safari your only browser

1. Delete Chrome, Firefox, Brave, DuckDuckGo and any other browser.
2. Turn on Limit Adult Websites and set up The Blocker in Safari.
3. Stop new installs: open Settings › Screen Time › Content & Privacy Restrictions › iTunes & App Store Purchases and choose restrictions for installing and deleting apps (Apple).
4. Ask someone you trust to set the Screen Time passcode.

The cost: you lose Chrome, and links inside other apps still open in their own browsers (see Instagram and TikTok’s in-app browsers). For the full lock-down, read how to make a porn blocker hard to turn off.

Fix 2 (Pro): Strong protection in every browser

To keep Chrome, use The Blocker Pro’s Strong protection. It uses Apple’s Screen Time (Family Controls, for your own iPhone) to set a web filter that iOS enforces, the same kind behind Limit Adult Websites. In the app’s words: “Adult sites stay blocked in Chrome, Firefox and other browsers, and in links you open inside apps like Instagram or X.”

• Outside Safari it uses Apple’s adult-content filter plus the first 50 sites on your own block list. The 50 is Apple’s limit: an app “can block up to 50 web domains” (Apple’s developer documentation).
• Blocked apps: apps you pick in Apple’s app picker stay closed while it is on. To keep Chrome out of reach without deleting it, put it here.
• Can’t delete The Blocker is on by default, and Hard moment blocks every website and your blocked apps for one hour, with no way to end it early.

Tap Block every browser and app on The Blocker’s Home screen and approve Apple’s Screen Time sheet; the status then reads “On in every browser and app”. Pro is $4.99 a month, $29.99 a year or $49.99 once (US prices; the App Store shows your local price).

Which option fits

What Strong protection can’t do

• Only Apple’s filter and your 50 sites outside Safari. The Blocker’s categories, keywords, schedules, ad lists and Always Allow list work in Safari only.
• It relies on iOS, and Apple says the filter limits “many” adult websites, not all. Apple doesn’t publish a list of covered browsers; if you find one where adult sites still load, write to hossam.hamoda@gmail.com.
• It can be switched back. Without a Screen Time passcode, anyone holding your phone can turn off The Blocker’s Screen Time access in Settings (the app then shows “Strong protection is paused”). Whoever holds the passcode can undo everything.
• It doesn’t filter feeds; see NSFW on X and Reddit.

On a child’s iPhone

Strong protection restricts the iPhone it runs on, for the person using it; it isn’t a parental control. For a child, use Screen Time through Family Sharing, where Limit Adult Websites is on by default under 18 (Apple). Google’s Family Link has a “Try to block explicit sites” setting for a child’s Google Account in Chrome, but Google warns the child “can sign out of Chrome”, and then its settings won’t apply (Google).
