If you use Chrome, the plugin you need is found exclusively on the Chrome Web Store. For Edge, the Chrome Web Store is also the correct source–Edge accepts Chrome-compatible plugins natively. Brave users should use the Brave extension store, which mirrors the Chrome repository. A direct installation from the store gives you the latest signed version, bypassing third-party risks.<br><br><br>To get the plugin for Chrome, navigate to the Chrome Web Store and search for the “Core” plugin (use that exact term). Click “Add to Chrome.” The same action applies to Brave and Edge through their respective stores. For Firefox, locate the official Firefox extension page. Do not use “for Chrome” files on Firefox–they are incompatible. The Firefox version is separate and must be fetched from the Mozilla repository only.<br><br><br>After selecting the appropriate store (Chrome Web Store, Firefox extension directory, or Brave add-ons), click the prominent “Add” or “Get” button. A pop-up will request permissions–review them, then confirm. The browser will automatically fetch and integrate the plugin. No manual file handling is required. If you attempt a side-load from an unknown site, the browser will block it for security. Always use the official store for the sole valid method.<br><br>Core Wallet Extension Install and Download Guide<br><br>For Chrome, open the Chrome Web Store and search specifically for the plugin name, avoiding generic results. Click the blue "Add to Chrome" button only after verifying the publisher matches the official project team, checking for a verified badge and a high rating count above 1,000. The browser will prompt you for permissions; review them to ensure they only request access to site data for specific crypto-related domains, not all sites. Once confirmed, the plugin begins downloading and automatically finalizes within seconds, appearing as an icon next to your address bar.<br><br><br>For Firefox, navigate to the Firefox Browser Add-ons portal instead of the Chrome Web Store. Search for the firefox extension directly, filtering results by "Recommended" or "By Firefox" to block imitation add-ons. Click "Add to Firefox" and await a pop-up window listing required permissions–most legitimate plugins need only host permission for specific URLs. Accepting triggers a download of the signed .xpi file, and Firefox will install it silently, placing a shortcut in the customise toolbar menu.<br><br><br>Brave users have a distinct advantage: since Brave is Chromium-based, you can directly use any plugin from the Chrome Web Store without additional steps. After clicking "Add to Chrome" on the store page, Brave’s internal system treats it as a brave extension. However, a quick check of the plugin ID in Brave’s extension management page (brave://extensions/) confirms it’s correctly installed. Edge users follow a near-identical method–open the Chrome Web Store in Edge, locate the desired plugin, and click "Allow extensions from other stores" if prompted. Edge installs it seamlessly, mirroring the Chrome download chrome process, but verify the plugin’s manifest version is 3 for optimal stability.<br><br><br>If a direct browser integration fails, resort to manual side-loading: download the .crx or .zip file from the official GitHub releases page, not a third-party repository. For Chrome, enable "Developer mode" in chrome://extensions/, then drag the .zip folder onto the page. Brave and Edge accept the same method; Firefox requires converting the plugin to a .xpi format via Mozilla’s signing tool. Always compare the checksum hash provided on the release page against your local file using a terminal command like `sha256sum filename`, as corrupted files may compromise security. After loading, pin the plugin icon to your toolbar using the puzzle-piece icon at the top right of your browser for rapid access.<br><br>Downloading the Official Core Wallet Extension from the Chrome Web Store<br><br>To begin, navigate directly to the Chrome Web Store for chrome browser builds and search using the specific developer name or the exact project identifier, bypassing generic search results that might show third-party or impersonating clones. The only legitimate listing will feature a verified publisher badge and show the plugin is a brave extension compatible, since Brave is Chromium-based. Click “Add to Chrome” to download chrome browser the package; the system will then install the plug-in automatically into your current session. For users running for edge or other Chromium forks, the same chrome web store link works without alteration, but you must manually confirm the permission prompts about reading site data–do not skip reviewing these requests.<br><br><br>If you prefer alternative browsers, note that this tool is also published as a firefox extension on the Mozilla Add-ons portal, requiring a separate install process because Firefox uses a different code base and signing mechanism. Download the firefox extension file (.xpi) directly from that official source; avoid dragging unsigned files or using developer mode unless you are testing locally. While the for chrome method remains the most direct path for the majority of users, the Firefox variant provides identical functionality concerning seed phrase management and dApp interaction, though update cycles may differ by days due to independent review queues.<br><br><br>Post-install, immediately access the brave extension or Chrome toolbar menu to pin the new icon for quicker access to your accounts. Verify the software has not been tampered with by checking its version number against the current stable release listed in the developer’s official documentation or GitHub repository. Download chrome browser plugin updates are handled automatically via the chrome web store, yet you can force a refresh by navigating to `chrome://extensions` and enabling “Developer mode” to click “Update.” Remember that a secure environment demands using only the latest version; older builds lack critical patching for disclosed vulnerabilities. For for edge users, the identical update mechanism applies under `edge://extensions` with no additional steps required to keep the firefox extension or Chromium counterpart current.<br><br>Q&A:  <br>I’m trying to find the official Core wallet extension, but I see a lot of similar-looking apps in the Chrome Web Store. How do I make sure I’m downloading the real one and not a fake or scam version?<br><br>This is a very common concern. To verify you are on the correct page, look at the publisher name. The official Core wallet extension for Avalanche is published by "Core." Check the total number of users—it should have millions, not thousands. Read the "Description" section carefully; the real extension will link directly to the official Core website (core.app). Avoid any extensions that ask for your private keys or a "seed phrase" during installation; a legitimate non-custodial wallet creates the phrase locally on your browser. If the URL in your browser bar is not `chrome.google.com/webstore` (or the official store for your browser), do not proceed. Finally, cross-reference the link on the official Core or Avalanche website before you install.<br><br>I’ve downloaded and installed the Core extension, but it’s asking me to create a password. What happens if I forget this password? Can I recover my wallet without it?<br><br>The password you set in the Core extension is only for local access on that specific browser and computer. If you forget this password, you will not be able to sign transactions or view your balances from that install. However, you can still recover your wallet. The recovery method is your 12 or 24-word secret recovery phrase (seed phrase), which you must write down and store safely when you first create the wallet. If you lose both the password AND the recovery phrase, your funds are lost permanently. So, treat the seed phrase as the master key. To avoid losing access, store the recovery phrase on paper in a secure location; never store it in a text file, screenshot, or cloud storage.<br><br>I use Brave browser, not Chrome. Will the Core wallet extension work on Brave? What about Firefox or Edge?<br><br>Yes, the Core wallet extension works on Brave because Brave is built on Chromium. You can install it directly from the Chrome Web Store while using Brave. For Microsoft Edge, the process is the same—go to the Chrome Web Store and click "Install" (Edge will guide you to allow extensions from other stores). The official Core extension is also available for Firefox, but you need to go to the Firefox Browser Add-ons store and search for "Core wallet." Do not use the Chrome Web Store link for Firefox. Performance on all Chromium-based browsers (Chrome, Brave, Edge, Opera) is identical. On Firefox, the interface looks the same, but some users report minor differences in pop-up window size.<br><br>I installed the extension, but when I try to connect it to a DeFi website like Pangolin, it doesn’t pop up. My other wallets like MetaMask work fine. What am I missing?<br><br>This usually happens because the website is trying to connect to an Ethereum-based wallet (like MetaMask), but Core defaults to the Avalanche network. First, make sure you have funded your wallet with at least a small amount of AVAX to pay for transaction fees. Second, check the extension icon in your browser toolbar. Click on it, then look at the "Network" dropdown at the top. If it is set to "Ethereum Mainnet," many Avalanche-native dApps (like Pangolin) will not detect it correctly. Switch it to "Avalanche C-Chain." Third, refresh the DeFi website tab after changing the network. If it still does not pop up, go to the extension settings (the gear icon), find the "Connections" or "Sites" section, and manually remove the site’s permissions, then try connecting again. Also, disable any other wallet extensions (like MetaMask or Phantom) temporarily to avoid conflicts.<br><br>I want to install Core on multiple computers. Do I have to create a new wallet each time, or can I use the same wallet across my laptop and desktop?<br><br>You can (and should) use the same wallet on multiple devices. On your first computer, create the wallet and immediately write down the 12-word secret recovery phrase. On your second computer, install the Core extension normally. When the extension starts, instead of selecting "Create New Wallet," select "Import Wallet" or "Recover Wallet." You will be asked for your recovery phrase; type it in exactly as written (all lowercase, with spaces). Your wallet will then appear on the second computer with the same addresses, balances, and transaction history. This does not create a "copy" of your wallet—it synchronizes the wallet via the blockchain. All transactions you sign on either computer will be broadcast to the network. Just remember that your transaction history will only display locally on the computer where you made those transactions.<br><br>I keep getting a "Download failed – network error" when trying to get the Core wallet extension from the Chrome Web Store. I have a stable Wi-Fi connection and other downloads work fine. What could be causing this and how do I fix it without using a VPN?<br><br>This specific error often comes from browser cache conflicts or extension permission blocks rather than your actual internet connection. First, completely close all Chrome windows, then clear your browser's cache and cookies for the last 24 hours (go to Settings > Privacy and Security > Clear browsing data, select "Cached images and files" and "Cookies and other site data", time range: "Last 24 hours"). After that, restart Chrome and try the download directly from the official Avalanche website ([https://extension-dapp.com/wallets/core-secure-core-wallet-extension-setup-guide-2.php Core Wallet setup guide].app) by clicking the "Add to Chrome" button there instead of searching the Web Store manually. If the error persists, check if your organization or antivirus software has a policy blocking Web Store downloads. Temporarily disable any aggressive firewall or ad-blocker extensions (like uBlock Origin or Privacy Badger) for the store domain, then try again. Do not use a VPN, as that can cause location-based restrictions. If nothing works, download the CRX file manually from the official Core GitHub repository under "Releases" (always verify the SHA-256 checksum against the official value listed on core.app), then drag and drop it into your Chrome Extensions page (chrome://extensions) with Developer Mode turned on. This bypasses the Web Store entirely.<br>
