Navigate to the Mozilla Add-ons store directly and search for the "Core" application. Do not use a generic search engine; use the store’s internal search to avoid fake plugins. Click "Add to Firefox" and confirm the prompt. After the download, a pop-up will ask for permissions; grant only the ones related to reading and changing data on specific websites (like dApps). Ignore any request for "access to all data." If you need a solution for Edge, the process mirrors the Chrome setup. Open the Edge Add-ons website and locate the "Core" plugin by its specific author name. Do not rely on search ranking–verify the publisher is correct. Click "Get" to initiate the download. A toolbar icon will appear after you accept the system dialog. For maximum security, disable automatic updates for this plugin in your browser settings and approve updates manually after checking community reviews. To download Chrome, head to the Chrome Web Store. Search for "Core" but filter results by "Extensions" only. Look for the entry with the highest number of users (over 50k is a baseline). Click "Add to Chrome." A window will appear listing required permissions–they should be limited to "Read and change data on coinmarketcap.com" and similar finance domains. If the plugin requests "identity" or "storage" without clear description, cancel the process and find a verified clone. The Brave extension should be added via the Chrome Web Store since Brave is Chromium-based. Do not use Brave’s built-in search; use the direct URL chrome.google.com/webstore. The download installs the same binary as for Chrome but integrates with Brave’s Shields. After adding, open brave://extensions and enable the "Allow access to file URLs" toggle if you manage local keys. This third-party tool will have a distinct icon–click it to generate a fresh address immediately. Install Core Wallet Extension Step by Step Guide Open the chrome web store first, because that is the only safe source for the authentic plugin. Type “Core” exactly into the store’s search bar and hit enter. Locate the official cryptographically signed app (developer name: “Core”), then click “Add to Chrome.” The download chrome prompt will appear; confirm it. A small icon will appear in your toolbar, indicating the plugin is now active on the browser. If you run a Chromium-based browser like Microsoft Edge, the same process applies: navigate directly to the chrome web store from within Edge’s address bar. The brave extension approach is also identical, as Brave natively supports all store listings. For both, you download the same package; there is no separate “for edge” or “for brave” version. After adding it, you must pin the icon to your toolbar for quick access–go to the puzzle piece menu and toggle the pin. Mozilla Firefox users have a different route. You cannot use the chrome web store for Firefox. Instead, use the official Mozilla Add-ons marketplace. Search for “Core” manually there, or use the direct listing link from the project’s website. This is a dedicated firefox extension–not a port–built specifically for Gecko engine compatibility. The plugin functions identically, but the installation flow requires a Firefox-specific trust prompt. After the download completes, a pop-up will ask you to grant permissions, specifically “Read and change all your data on the websites you visit.” You must accept this–without it, the tool cannot sign transactions on dApps. Also, verify you have at least 500 MB of free disk space; the plugin stores chain data locally for the integrated browser node. If you skip this, the interface will remain stuck on “Syncing” indefinitely. Finally, avoid fake copies. Never use a third-party download link from an article or a YouTube description. The only safe method is a direct extraction from the chrome web store (or Mozilla store for the firefox extension). After installation, open the extension popup and write down your seed phrase manually–do not copy-paste or screenshot it. This completes the deployment of the node client onto your for chrome or for edge browser environment. Downloading the Correct Version for Your Browser and Operating System First, identify your browser. For Google Chrome, navigate directly to the Chrome Web Store and search for the specific plugin you need. Use the official store link, not a third-party site. For Microsoft Edge, the process differs: edge users must open the Edge Add-ons store. Do not attempt to download chrome files for an edge browser–they are not compatible. The Chrome Web Store is the only secure source to download chrome plugins. For Firefox, you must use the official Firefox Browser Add-ons portal. Searching for a “firefox extension” on a general search engine may lead to counterfeit files. Verify the publisher’s name matches the developer’s official site before clicking any button. Opera and Brave users have distinct paths. Opera requires using its own addon store, while for brave extension installation, you can often use the chrome web store directly. Brave is Chromium-based, so it supports most chrome plugins, but always confirm the extension listing shows “compatible with Brave” or “works with Brave” in its description. Check your browser type: Chrome, Edge, Firefox, Opera, or Brave. Open the respective official store (Chrome Web Store for chrome and brave; Edge Add-ons for edge). Search using exact plugin name; avoid generic terms like “plugin download”. For users on a Chromium-based browser other than Chrome, such as Brave or Vivaldi, the chrome web store remains your primary resource. However, certain plugins may be flagged as “for chrome only” and might require manually enabling developer mode in brave extension settings to load unpacked files. Never use a “download chrome” link if you are on an alternative OS like Linux or macOS–auto-detection tools can fail. Specifically, do not rely on browser auto-download features when picking the plugin. Many fake sites disguise malware as a “brave extension” or “firefox extension”. Manually copy the plugin ID from the developer’s documentation and paste it into the store’s search bar. This eliminates guesswork and prevents downloading the wrong build. Windows: all browsers support standard builds. macOS: only Safari-specific builds differ; for other browsers, the chrome web store version works. Linux: verify the extension supports your distro; some plugins require manual checksums. Finally, after locating the correct listing, click the “Add to [browser]” button–not a “download” button on a third-party page. The store will handle the installation automatically. If prompted, confirm the permissions match the intended functionality; no legitimate plugin asks for excessive access. This ensures you have the precise version for your system and browser without risk. Q&A: I’m trying to install the Core wallet on my laptop, but after I download the file, it asks me to choose between "Core" and "Core Testnet." Which one should I pick? Pick "Core." The "Core" option is for the main Avalanche network, which handles real transactions and real AVAX tokens. "Core Testnet" is a separate sandbox environment where developers test new features or users can practice without using real money. If your goal is to set up a wallet to receive, send, or store actual AVAX, you want the main version. When you open the extension after installation, you’ll also see a small toggle to switch between networks, so you can explore the testnet later if you want, but start with the main one for your real wallet. I clicked "Create a New Wallet" inside the extension, and it showed me a 12-word seed phrase. Do I really need to write that down on paper? Isn't saving it in a Google Doc fine? Write it down on paper. Saving that phrase in a Google Doc, a notes app, or an email draft puts it at risk if your account gets hacked or your device gets a virus. If someone gets that file, they can steal everything in your wallet from any computer anywhere. The 12-word phrase is the single key to all your funds. If you lose it, the company behind the wallet cannot help you recover it. Paper hidden in a safe place (like a fireproof safe or a lockbox) is the safest bet for most people. If you absolutely need a digital backup, encrypt the file with strong software and store it offline, but paper is simpler. I followed the guide and got the extension installed, but I’m confused. When I try to receive AVAX from a friend, it shows me a long string of letters and numbers. Is that really my address? Do I need to use the "C-Chain" option? Yes, that long string of letters and numbers is your address, and yes, you should use the "C-Chain" address for most transactions. When you click "Receive" in the Core extension, it will show you your address and let you copy it. The "C-Chain" is where regular people send and receive AVAX if they are using the network normally. If you copy the address that starts with "0x" (similar to Ethereum addresses), that is the C-Chain address. Make sure your friend is also sending to a C-Chain address. If they send from an exchange, 99% of the time the exchange will ask them to pick "Avalanche C-Chain." If you use the wrong chain (like the X-Chain or P-Chain), the transaction will still show up on the Explorer, but your wallet might not display the balance until you switch networks. Stick to C-Chain for standard transactions. My Core wallet is installed and I can see it in my browser toolbar. But when I close the browser and reopen it, I have to type my password again. Is that normal? How do I stop it from asking every time? It is normal behavior. The Core extension locks itself when you close your browser to protect your funds if someone else uses your computer or if you visit a malicious website. You cannot fully stop it from asking for your password after a browser restart, and you should not try to bypass that. However, you can adjust how often it locks. Click on the extension icon, go to the Settings menu (usually a gear icon), and look for "Auto-Lock." Here you can set a longer timeout, like 30 minutes or 1 hour of inactivity. This means if you switch tabs or step away for a few minutes, it won't ask for the password immediately when you come back. But if you close the browser entirely, it will always lock for security reasons. A good middle ground is to set the timeout to 15 minutes so you don't have to enter your password every five seconds.
