How to Install MetaMask for Firefox: A Step-by-Step Guide MetaMask is a leading non-custodial cryptocurrency wallet that allows you to interact safely with the Web3 ecosystem, manage digital assets, and connect seamlessly to decentralized applications (dApps). Setting up this powerful tool as a browser extension takes just a few minutes.
This step-by-step guide will walk you through downloading, installing, and securing your MetaMask wallet on the Mozilla Firefox browser. Step 1: Visit the Official MetaMask Website
Always download crypto wallets directly from verified sources to avoid malicious clones and phishing scams. Launch your Firefox browser. Navigate to the official website: metamask.io/download.
Ensure the URL is correct and displays a secure connection lock icon in your address bar. Step 2: Add the Extension to Firefox
Once on the download page, the website will automatically detect that you are using Firefox. Click the Install MetaMask for Firefox button.
You will be redirected to the official Firefox Add-ons Store page for MetaMask. Click the blue Add to Firefox button.
A Firefox pop-up will appear requesting permissions (such as accessing data for websites and showing notifications). Click Add to confirm the installation. Step 3: Begin the Wallet Setup
Once the extension downloads, a new browser tab will automatically open featuring the iconic MetaMask fox. Click the Get Started or Let’s get started button.
Review MetaMask’s data collection terms and click I Agree to proceed. You will be presented with two choices:
Import an existing wallet (if you already have a 12-word seed phrase).
Create a new wallet. Select Create a new wallet for a fresh setup. Step 4: Create a Strong Password
This password unlocks the MetaMask extension locally on your computer. It does not act as your master recovery key.
Type a unique, strong password containing letters, numbers, and symbols.
Confirm your password, check the terms of use box, and click Create a new wallet. MetaMask Wallet Extension Setup Tutorial (2025)
