&lt;div&gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;img  width: 750px;  iframe.movie  width: 750px; height: 450px; &amp;lt;br&amp;gt;Core wallet extension install and download guide&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Core wallet extension install and download guide&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Open the Chrome Web Store directly from your Chrome or Brave browser. For Chrome, type chrome web store into the address bar. For Brave, the store is accessible from the menu under “Extensions” or by visiting the same URL. Do not search for the tool via Google; always use the official store listing to avoid fake copies. The same procedure works for Firefox extension installation via the Mozilla Add-ons site, and for Edge via the Edge Add-ons store.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;To download Chrome or Brave extension, locate the entry marked “Crypto Core” – or more commonly “Core” – in the store. Click the blue “Add to Chrome” button. A prompt will appear listing the permissions the plugin requests; these usually include “Read and change data on a few sites” to interact with dApps. Accept them. The plugin size is under 5 MB and the install completes in under 30 seconds on a standard broadband connection.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;For Firefox extension users, the process is identical: visit the Firefox Add-ons site, search for the plugin by its exact name, and click “Add to Firefox.” For Edge, the install path goes through the Edge Add-ons store, where the “Get” button triggers the download. After installation, a popup opens automatically. You will see a 12-word recovery phrase; write it down on paper immediately. Do not save it digitally. This phrase is the only way to restore access if the plugin is removed or the browser is reset.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Core Wallet Extension Install and Download Guide&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;To add this tool to your browser, open the Chrome Web Store directly and search for the official plugin by its publisher. Avoid third-party sources. For Chrome, click “Add to Chrome” and confirm the permission prompt. The same process applies for any Chromium-based browser, including a Brave extension setup–simply follow the Chrome Web Store link. After the download, a pop-up will confirm the plugin is pinned.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;If you use Firefox, visit the Firefox Browser Add-ons portal. Locate the listing by the verified developer, then click “Add to Firefox.” A permissions dialog will list required access rights; review these before confirming. The plugin will appear in your toolbar. For a seamless experience on Firefox, ensure your browser version is 115 or newer, as older versions may lack necessary API support. The total file size for this add-on is under 5 MB.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;On Chrome, after the download, navigate to `chrome://extensions` to check the plugin is active. Toggle “Developer mode” only if you need manual control–otherwise, leave it off. The extension will auto-update. For Brave, the Brave extension behavior mirrors Chrome: pin it from the puzzle icon in the top-right. If the plugin fails to load, clear your browser cache and restart. The Chrome Web Store page lists the exact version number, which you can cross-check with the installed one.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;For a manual Firefox installation, download the XPI file directly from the developer’s official site (not the store), then drag it into the `about:addons` page. This method is useful if you need a specific older version. The plugin supports both Chrome and Firefox securely, but avoid searching for “Core wallet” in random directories–only use the official storefronts. The download is a single click on Chrome; on Firefox, you may need to allow pop-ups from the store temporarily.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Official Sources for Core Wallet Extension Download&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Use the Chrome Web Store for download chrome variant of the browser plugin. This is the only verified distribution channel for Chromium-based browser add-ons. Any link outside of this store risks installing a counterfeit plugin that intercepts private keys.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Navigate to the official Chrome Web Store listing for the brave extension or Chrome version. Verify the publisher identity matches the project’s GitHub organization.&amp;lt;br&amp;gt;For firefox extension, go directly to the Mozilla Add-ons (AMO) site. Mozilla manually reviews each submission for security compliance.&amp;lt;br&amp;gt;If you need the add-on for edge, open the Microsoft Edge Add-ons store. Edge also accepts Chrome Web Store listings, but the native Microsoft store guarantees automatic updates through your browser.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Always check the URL bar before clicking “Add to Browser.” The correct store URL must begin with &amp;quot;chrome.google.com/webstore&amp;quot; for download chrome actions, or &amp;quot;addons.mozilla.org&amp;quot; for Firefox. Any variation with a different domain is phishing.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Brave Extension – Downloaded from the Chrome Web Store, as Brave is Chromium-based.&amp;lt;br&amp;gt;Firefox Extension – Sourced exclusively from AMO.&amp;lt;br&amp;gt;For Edge – Use the Edge Add-ons store or install the Chrome Web Store version via a one-time permission.&amp;lt;br&amp;gt;Download Chrome – Directly from Chrome Web Store listing.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Never initiate a download from a pop-up ad, a forum post, or an unofficial GitHub release. The only files you should install are those retrieved from the official stores listed above. The GitHub repository itself provides no direct download link for the plugin; it redirects to the Chrome Web Store or AMO.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;The brave extension and firefox extension share identical codebases but receive separate version tags in their respective stores. If you switch from a browser like Chrome to Brave, uninstall the old plugin first, then re-install from the Brave Web Store (which mirrors the Chrome Web Store).&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;For download chrome version, click “Add to Chrome” only after confirming the publisher email matches the official project domain. The same applies when you choose the add-on for edge – verify the “Offered by” field matches the project’s official contact.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Avoid third-party aggregator sites that claim to offer “one-click” install for multiple browser versions. These aggregators repackage the plugin without security audits. The only safe download source is the store specific to your browser.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Q&amp;amp;A:  &amp;lt;br&amp;gt;I downloaded the Core wallet extension file, but my browser says it can’t install it because the file is corrupt or the extension is not from the Chrome Web Store. What am I doing wrong?&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;This usually happens when you download a generic zip file from a third-party site instead of the actual extension package. The Core wallet should be installed directly from your browser’s official extension store. For example, on Chrome, you go to the Chrome Web Store and search for &amp;quot;Core Wallet&amp;quot; by Ava Labs. You click &amp;quot;Add to Chrome.&amp;quot; If you already downloaded a file from a random website, delete it. Your browser warning you about a corrupt file is a good sign—it means you avoided a malicious download. Go to the official store, install it there, and the process takes about 30 seconds. After that, you will see the fox icon appear in your toolbar.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;I am trying to install the Core wallet extension on my work laptop, but the IT department blocks all extensions. Is there a way to run it as a standalone app instead of a browser extension?&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Yes, there are two workarounds for this. First, you can download the Core desktop application from the official Avalanche website. This is a full program you install on your computer like you would with Spotify or Zoom. It does not need a browser extension to function. Second, you can use the web version of Core at app.core.app. You will need to connect a hardware wallet like a Ledger or use a mobile wallet to scan a QR code. However, if your company’s security policy blocks all third-party software and websites, you should get permission before installing anything. Installing the desktop app bypasses the browser block, but your IT team might still detect it.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;I followed the guide and installed Core on Brave browser. Now I want to move it to Firefox. Do I have to uninstall it from Brave first? And will I lose my wallet balance if I do that?&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;You do not have to uninstall the Brave extension first. You can have the Core wallet installed on multiple browsers at the same time. Your wallet balance is not stored inside the extension; it lives on the blockchain. What the extension holds is your private keys (the password to access your funds). When you install Core on Firefox, you will be asked to either create a new wallet or import an existing one. To keep your funds, choose &amp;quot;Import Wallet&amp;quot; and enter your 12-word secret recovery phrase. Do not lose that phrase. If you uninstall the Brave extension without saving your recovery phrase, you will lose access to your funds permanently, even though the balance still exists on the blockchain. So, to answer your question: install Firefox first, import your phrase, confirm you can see your balance, then you can delete the Brave extension if you want.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;I installed the Core extension last week and it worked fine. Today, it shows a red error badge and says &amp;quot;Network Error.&amp;quot; Do I need to reinstall the whole thing?&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Reinstalling is a last resort. Nine times out of ten, this is a network or RPC issue, not an installation problem. Try these steps in order: First, check your internet connection. Second, click the Core icon, go to settings (the gear icon), then select &amp;quot;Networks.&amp;quot; Make sure the network is set to &amp;quot;Mainnet&amp;quot; and not a test network or a custom RPC that might be down. Third, restart your browser completely. If the red badge is still there, go to your browser’s extension manager (chrome://extensions), find Core, and click &amp;quot;Update.&amp;quot; This forces the extension to download the newest version from the store. Only if none of that works should you remove the extension and reinstall it. Remember: reinstalling will wipe the extension’s local data, so make sure you have your recovery phrase saved before you delete it.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;I only have a 12-word seed phrase from an old MetaMask wallet. Can I use that phrase to set up the Core wallet extension, or do I have to create a completely new wallet inside Core?&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Yes, you can use your old MetaMask seed phrase. The Core wallet extension uses the same industry standard (BIP-39 protocol) for generating wallets. When you open Core for the first time, select &amp;quot;Import Wallet&amp;quot; instead of &amp;quot;Create New Wallet.&amp;quot; Enter your 12-word phrase. Core will then scan for your addresses and display your balance. However, there is one common surprise: Core might not show your tokens right away. After importing, you often need to add the token contract address manually (for example, if you hold USDC or AVAX) because [https://web3-Extension.com/wallet/core.php Core Wallet Edge extension] does not auto-discover all tokens like MetaMask sometimes does. Once you add the token, your balance appears. This import method is safe because you are only telling the extension to use the same keys—you are not sending your coins anywhere.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;I’m trying to download the Core wallet extension from the Chrome Web Store, but it says “This extension is not from the Chrome Web Store” and blocks the install. What am I doing wrong?&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;This error typically happens because you’re trying to install the extension from a third-party download site or a direct .crx file link, which Chrome now blocks by default for security reasons. The Core wallet extension is a legitimate wallet built by the Avalanche team, but you must install it only from the official Chrome Web Store page (or the Brave/Mozilla add-on stores if you use those browsers). Open a new tab, go directly to the Chrome Web Store, and search for “Core” by “Ava Labs.” The one with the verified publisher badge is correct. Click “Add to Chrome” directly from that page. If you still see the block error, make sure your Chrome version is up to date, and check that “Developer mode” in your extensions settings is turned OFF (it can cause false warnings for official extensions). Also, temporarily disable any third-party antivirus that might be intercepting the download. The official install process takes about 10 seconds and should show a confirmation popup asking for permissions related to reading clipboard data and accessing website data (needed for wallet functions). If you’re using a firewall or corporate VPN, it might also block the Web Store connection, so try a regular home network. After the green checkmark appears, the Core icon should show up in your browser toolbar.&amp;lt;br&amp;gt;&lt;/div&gt;</summary>
