First-Time Setup: Create, Restore, and Secure

Create a New Wallet

Open the Phantom Wallet Extension Firefox and select Create New Wallet. Save the generated seed phrase offline: write it on paper and store it in two separate secure locations. Create a strong password for quick unlocks in Firefox. Never share your seed phrase or store it in cloud notes or screenshots.

Import an Existing Wallet

Select Import Wallet to restore using your seed phrase. Phantom will rebuild your addresses across supported networks. If you previously used Phantom on another browser, you can also export a private key or use the seed phrase to sync your accounts into Firefox.

Strengthen Security

• ✅ Create a long, unique password just for Phantom.
• ✅ Enable auto-lock with a short timeout if you step away.
• ✅ Consider a hardware wallet (Ledger) for large balances or frequent signing.
• ✅ Turn on phishing and spam protection in settings.

Connect Ledger (Optional)

Open Phantom settings in the extension, choose Connect Hardware Wallet, and follow the prompts. On Firefox, ensure you have the latest Ledger firmware and the correct app (Solana, Ethereum, or Polygon) open on your device before connecting.

Using Phantom on Firefox: From Tokens to NFTs

Send and Receive Crypto

Click Send to transfer tokens, paste the recipient address, choose the network, set the amount, and confirm. Use the Receive tab to display your address or QR code. Always double-check the correct network and address formatting before finalizing the transaction.

Swap Inside the Wallet

Phantom’s built-in swaps let you trade supported tokens without leaving the extension. Review the quoted price, slippage, and network fees. Transaction simulation previews what will happen before you approve, helping you avoid surprise approvals and malicious contracts.

NFT Gallery and Spam Controls

Your NFTs display in a clean gallery view with collection data and metadata. Hide or report suspicious items with one click to keep your collection uncluttered. When transferring NFTs, confirm the network and recipient to ensure safe delivery.

Connect to dApps

On a dApp site, click Connect Wallet and choose Phantom. The Phantom Wallet Extension Firefox prompts you to approve the connection and permissions. You can review or revoke connections anytime in your settings to maintain tight control over your wallet.

Stake and Earn

Stake SOL to validators within Phantom to help secure the network and earn rewards. Review validator performance and fees before delegating. You can also discover DeFi protocols across ecosystems and connect instantly via Phantom on Firefox.

Security, Privacy, and Best Practices

• 🔒 Seed phrase safety: Store offline only. Never share it. Phantom support will never ask.

Always verify the publisher as “Phantom Technologies, Inc.” and follow links from Phantom’s official website. If it is temporarily unavailable in your region, consider using the Phantom extension on a supported browser or the mobile app.

How do I verify I am installing the legitimate Phantom extension?

Install only from the official Mozilla Add-ons listing linked from Phantom’s website. Check the publisher name, reviews, version history, and website link. Never install from pop-ups, ads, or random direct-download files. Phantom support will never DM you a file.

Does Phantom on Firefox support Solana, Ethereum, and Polygon?

Phantom supports Solana, Ethereum, and Polygon in a single interface. You can switch networks from the wallet header or settings, view balances separately, and connect to dApps across ecosystems. Always confirm the network before sending tokens or NFTs.

Can I migrate my wallet from Chrome to Firefox?

Yes. Export your seed phrase or the relevant private keys from your existing Phantom installation, then import them into the Phantom Wallet Extension Firefox. Confirm that addresses and balances appear as expected. For large holdings, test with a small transfer first.

What should I do if transactions fail or get stuck?

First, confirm you are on the correct network and have enough gas/fees. Try refreshing the dApp, resetting the nonce (EVM), or waiting for network congestion to clear. If problems persist, review approvals, update Phantom and Firefox, and consult network explorers to diagnose.

Does Phantom on Firefox work with Ledger hardware wallets?

Yes, you can connect Ledger for supported networks on desktop. Update Ledger Live, install the chain app (Solana, Ethereum, or Polygon), unlock the device, open the app, then pair via Phantom settings. Sign critical transactions with Ledger for maximum security.

How do I remove or reset the Phantom extension in Firefox?

Back up your seed phrase first. In Firefox, open Add-ons, find Phantom, and choose Remove. To reinstall, add it again from the official listing and import your wallet with the seed phrase. Never proceed without a verified backup of your recovery phrase.
