You’ve probably tried it. You open Chrome on your Android or iPhone, head to the Chrome Web Store, find that perfect ad blocker or productivity tool, and then... nothing. The "Add to Chrome" button is either grayed out or just plain missing. It's annoying. We’ve been using desktop extensions for twenty years, yet Google Chrome extensions on mobile remain a weirdly guarded gate. Why?
The short answer is that Google officially doesn't support them. If you’re looking for a simple toggle in the settings of the standard Chrome app to enable your favorite desktop tools, you won't find it. It's not there. Google cites "performance and security" concerns, but let’s be real—part of it is about maintaining control over the mobile ad ecosystem.
But wait. There’s a loophole. Actually, there are several.

While the official Chrome app is a dead end for extensions, the underlying engine—Chromium—is open source. This has allowed a handful of rogue, brilliant developers to build their own browsers that look and feel exactly like Chrome but actually let you install desktop extensions. If you’re willing to hop over to a different app icon, you can have your Ublock Origin, Dark Reader, and LastPass running on your phone by dinner time.
Why Chrome Extensions on Mobile Are Such a Headache
It basically comes down to how mobile processors handle memory. Back in the day, phones would choke if you tried to run a dozen background scripts alongside a heavy webpage. Desktop Chrome is famous for eating RAM; Google didn't want that reputation following them to the early Pixel or Nexus phones.
Even now, with phones having 12GB of RAM, Google sticks to its guns. They argue that extensions could drain your battery or, worse, scrape your private data without the strict sandboxing that mobile apps usually require.
There is also the "Manifest V3" drama. Google is pushing a new standard for extensions that limits what they can do, specifically to make ad blocking harder. Allowing full, unrestricted desktop extensions on mobile would essentially hand users a "delete all ads" button for the mobile web, which isn't exactly great for Google's bottom line.
The Chromium Alternatives That Actually Work
If you want Google Chrome extensions on mobile today, you have to stop using the official Chrome app. It's the only way.
Kiwi Browser is the gold standard here. Developed by Arnaud Granal, it’s a Chromium-based browser that looks nearly identical to Chrome but has a dedicated "Extensions" menu. You can go straight to the Chrome Web Store, click install, and it just works. I’ve used it for bypass paywall scripts and specialized SEO tools that usually require a laptop. It’s snappy. It doesn't feel like a janky workaround.
Then there’s Yandex Browser. It’s popular in Eastern Europe and has surprisingly robust extension support. However, some users get twitchy about the privacy implications of using a Russian-based browser. That’s a fair concern.
Missive and Flow are newer players, but for the most part, if you are an Android user, Kiwi is where you start and end your search.
What About iPhone Users?
Apple users are in a different boat. A much more restricted, fancy boat.

Because of Apple’s App Store rules, every browser on iOS—whether it’s Chrome, Firefox, or Opera—must use the WebKit rendering engine. They are basically Safari with a different skin. Because of this, you cannot run "Chrome" extensions on an iPhone.
But don't give up yet.
Safari has its own "Web Extensions" ecosystem now. Since iOS 15, you can actually go into your iPhone settings, find Safari, and add extensions. They aren't the exact same files you find in the Chrome Web Store, but many developers (like the team at 1Password or Honey) have ported their code over. It’s the closest you’ll get to the desktop experience on an Apple device.
The Security Risk Nobody Mentions
Let’s talk about the "kinda" scary part.
When you install Google Chrome extensions on mobile through a third-party browser like Kiwi, you’re stepping outside of Google’s "Safety Check" bubble. Not every extension is optimized for a touch interface. Some can cause the browser to crash, and others might be "permission hungry."
If an extension asks for permission to "read and change all your data on all websites," it means exactly that. On a desktop, we’re used to this. On a mobile phone, where your banking apps, private messages, and saved passwords live, the stakes feel higher. Stick to well-known, open-source extensions. If a random "Discount Coupon Finder" with three reviews asks for access to your data, delete it.
Performance Hits are Real
Honestly, your phone might get hot. If you load up a mobile browser with ten different extensions, you’re going to see the battery percentage drop faster than usual. Desktop extensions are often poorly optimized for mobile sleep cycles. They keep the CPU awake.
I usually recommend keeping it lean:
- One solid ad blocker (uBlock Origin is the goat).
- One password manager.
- Maybe one specialized tool (like a "dark mode" force-enabler).
Anything more and you’re basically turning your phone into a space heater.
The Future: Will Google Ever Give In?
There are rumors. There are always rumors.
With the rise of foldable phones and "desktop modes" like Samsung DeX, the line between a phone and a computer is blurring. People are demanding more power. We’ve seen Microsoft Edge on mobile start testing limited extension support in certain regions (like China). Since Edge is also Chromium-based, this puts massive pressure on Google to keep up.
If Google wants the "Pro" version of their Pixel phones to be taken seriously as productivity machines, they’ll eventually have to allow at least a curated list of extensions. But for now, we’re stuck with the workarounds.
How to Get Started Right Now
If you are ready to stop waiting for Google and want your extensions today, follow this path.
First, go to the Play Store and download Kiwi Browser. Don't worry about the name; it's built on the same engine as Chrome. Once you open it, tap the three dots in the top right corner and select "Extensions."
From there, you'll see a link to the "Google" or "Chrome Web Store." It will look exactly like it does on a PC. Zoom in, find your extension, and hit "Add to Chrome."

You’ll get a pop-up asking for permissions. Accept it. Now, to actually use the extension, you usually have to go back to that three-dot menu and scroll all the way to the bottom. Your installed extensions will live there, tucked away below the standard settings.
For iPhone users, your path is different. Open your Settings app, scroll down to Safari, and tap Extensions. Tap More Extensions to see what’s available in the App Store. It’s a smaller selection, but it’s stable and won't wreck your battery life.
Actionable Next Steps:
- Audit your needs: Decide if you actually need a full extension or if a specialized "Privacy Browser" like Brave or DuckDuckGo (which have built-in blocking) would solve your problem faster.
- Test Kiwi Browser: If you’re on Android, install it and try just one extension first. See how it affects your speed before going overboard.
- Check Safari Gallery: If you're on iOS, check the Safari extension store for "Userscripts." It’s a powerful app that lets you run custom Javascript, mimicking many Chrome extension features.
- Stay Updated: Keep an eye on the "Chrome Canary" builds for Android. Google often tests features there months before they hit the mainstream app; this is where extension support will likely appear first if it ever happens.
