Installing MetaMask on Google Chrome
Follow these steps to add MetaMask as an extension to your Chrome browser:

- Download the Extension: Click “Download” and select “Chrome.”
- Add to Chrome: A prompt will appear; click “Add to Chrome,” then confirm by clicking “Add Extension.”
- Launch MetaMask: Once installed, click the fox icon in your browser toolbar to open the wallet.

- Create a Password: Set a strong password to protect your wallet locally.
- Backup Recovery Phrase: Write down your 12-word recovery phrase and store it offline—this is crucial for wallet recovery.
🔐 Security Tip: Never share your recovery phrase with anyone. MetaMask will never ask for it.
After setup, you can begin exploring dApps, swapping tokens, or connecting to NFT marketplaces directly from your browser.
Installing MetaMask on Firefox
The process on Firefox is similar but uses Mozilla’s add-on system:
- Visit addons.mozilla.org and search for “MetaMask.”
- Locate the official MetaMask extension (verified by Mask Network).
- Click “Add to Firefox” and confirm installation.
- Launch the extension from the toolbar and follow the same setup steps as above.
Firefox users benefit from enhanced privacy features, making it a solid choice for security-conscious Web3 explorers.
Installing MetaMask on Opera
Opera comes with built-in Web3 support, but you can still install MetaMask for full functionality:
- Open Opera and go to the Extensions menu (
opera://extensions). - Enable Developer Mode.
- Click “Load unpacked” and select the extracted MetaMask folder if manually downloaded (not recommended unless necessary).
- For most users, simply visiting metamask.io and installing the extension works seamlessly.

How to Download MetaMask on Mobile Devices
MetaMask also offers a powerful mobile app for iOS and Android, allowing you to manage your crypto on the go while maintaining full control over your assets.
Step 1: Download the Official App
- For iPhone Users: Open the Apple App Store, search for “MetaMask,” and ensure you’re downloading the version published by Consensys Software Inc. Look for over 50,000 reviews as a trust signal.
- For Android Users: Visit the Google Play Store, search “MetaMask,” and verify the developer name is Consensys.
⚠️ Warning: Avoid unofficial apps or clones that mimic MetaMask. Only download from verified app stores.
Tap “Install” and wait for the download to complete.
Step 2: Create or Import Your Wallet
Upon opening the app:
- Tap Create a Wallet (for new users) or Import Wallet (if you already have a recovery phrase).
- Accept terms and conditions.
- Set a strong password or biometric lock (Face ID, fingerprint).
- Carefully write down your 12-word recovery phrase in order—store it offline and securely.
- Confirm the phrase by selecting words in the correct sequence.
This recovery phrase is your lifeline—if lost, there’s no way to recover your funds.
Step 3: Fund Your Wallet
Once set up, you can:
- Buy crypto directly using a debit/credit card through integrated providers like Transak or MoonPay.
- Receive funds by sharing your public wallet address.
- Transfer assets from centralized exchanges like OKX or Coinbase.
