If MetaMask crashes, closes immediately, freezes, or shows a blank window in Chrome, start with the reversible fixes: restart Chrome, update Chrome and MetaMask, disable competing wallet extensions, and test whether the problem occurs outside a single dapp.
Do not uninstall, reset, or clear MetaMask data until you have securely backed up your Secret Recovery Phrase and the private keys for any separately imported accounts. MetaMask cannot recover a lost Secret Recovery Phrase.
Quick fix: try these first
- Close MetaMask and quit Chrome completely, then reopen Chrome.
- Update Chrome at
chrome://settings/helpand relaunch it. - Open
chrome://extensionsand confirm MetaMask is enabled. - Temporarily disable other wallet extensions and restart Chrome.
- Open MetaMask directly from the toolbar without connecting to a dapp.
First, identify what is actually crashing
“MetaMask crashing” can describe several different problems. The correct fix depends on the symptom:
| Symptom | Most likely area to investigate |
|---|---|
| The popup closes immediately | Extension state, Chrome profile, or a conflicting extension |
| A full MetaMask tab is blank, black, or stuck loading | Extension state, browser profile, or update compatibility |
| Chrome becomes slow or freezes when MetaMask opens | Chrome, extension interactions, or profile problems |
| MetaMask works until one dapp opens | That dapp, its permissions, or an injected-wallet conflict |
| The wallet opens but balances or transactions fail | Network, RPC, gas, dapp, or hardware-wallet issues |
| Only Ledger or Trezor actions fail | Hardware-wallet connection, firmware, USB, or compatibility |
| Chrome disables or calls the extension corrupted | Extension installation, Chrome policy, or a managed device |
MetaMask is officially supported on Google Chrome, Firefox, and Chromium-based browsers, with the project recommending the latest available browser version. Chrome extensions are desktop extensions; switching a mobile browser to “desktop mode” does not install the Chrome extension. See MetaMask’s supported-browser documentation and Google’s Chrome Web Store guidance.

Before reinstalling: protect wallet access
Reinstalling removes your local extension access. Your assets remain on the blockchain, but recovery depends on having the correct recovery information.
- Confirm that your Secret Recovery Phrase is available, legible, and stored securely.
- Record the private keys for accounts imported separately. A Secret Recovery Phrase does not necessarily restore every imported account.
- Never enter the phrase or a private key into a website, support form, screenshot, cloud note, email, or chat.
- Do not give recovery information to anyone claiming to be MetaMask Support. MetaMask cannot recover a lost phrase.
- Do not delete your original Chrome profile until you have verified wallet access elsewhere.
MetaMask explains recovery phrases and imported accounts in its official FAQ.
Step-by-step troubleshooting
1. Restart MetaMask and Chrome
Close any MetaMask popup or full-page tab. Quit Chrome completely, reopen it, and launch MetaMask from the toolbar. If it remains unresponsive, open chrome://extensions, toggle MetaMask off, wait a few seconds, and toggle it back on. This is safer than resetting wallet data.

- Open Chrome’s three-dot menu.
- Choose Help → About Google Chrome.
- Allow Chrome to check for and install updates.
- Select Relaunch, then test MetaMask.
You can also open chrome://settings/help. Menu wording can vary slightly by operating system and Chrome release.
3. Check MetaMask’s official listing
Open chrome://extensions and confirm MetaMask is enabled. Check the official Chrome Web Store listing for the current version and update date. The listing observed on August 18, 2026 showed version 13.43.0, updated August 12, 2026; this is a changeable listing detail, not a permanent version claim.
Do not download an extension package from an unofficial site. The official listing’s extension ID is nkbihfbeogaeaoehlefnkodbefgpgknn.

4. Disable competing wallet extensions
Multiple wallet extensions can compete for dapp connection requests or inject competing wallet providers into webpages. This does not prove that another extension caused the crash, but disabling them is a useful, reversible diagnostic.

- Re-enable extensions one at a time if you need to identify an interaction.
MetaMask discusses this issue in its installation guidance and dapp troubleshooting documentation.
5. Test without a dapp
Open MetaMask on a neutral webpage without connecting to anything. Then try a second, trusted dapp. Do not use random “test” websites while troubleshooting.
- Crashes everywhere: investigate Chrome, the extension, the Chrome profile, or local extension state.
- Works directly but fails on one dapp: investigate that dapp, its permissions, provider conflicts, or compatibility.
- Fails only while signing or transacting: investigate network, gas, hardware-wallet, or dapp issues rather than assuming the extension is crashing.
MetaMask’s troubleshooting hub separates extension, connectivity, blockchain-host, balance, error-code, and dapp problems.

6. Try a fresh Chrome profile
A fresh profile is a cleaner diagnostic than deleting cookies or clearing all browser data. Select the Chrome profile icon, create a new profile, and install MetaMask only from MetaMask’s official site or its official Chrome Web Store listing. Test the extension without importing funds or connecting to unknown sites.

If MetaMask works there, the original profile, its extension state, policies, cached data, or extension interactions may be involved. This is a practical diagnostic inference, not a confirmed MetaMask finding. Do not delete the old profile until recovery has been verified.
7. Try another supported Chromium browser
Testing another supported Chromium-based browser can show whether the problem is specific to the Chrome installation or profile. It does not prove that the other browser is permanently safer or more compatible. Import the wallet only after verifying your recovery phrase and imported-account keys.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.When reinstalling MetaMask is appropriate
Reinstall only after Chrome and MetaMask are updated, competing extensions are disabled, the problem is not limited to one dapp, and recovery material has been verified.
- Secure the Secret Recovery Phrase and separately imported account keys.
- Remove MetaMask from Chrome.
- Restart Chrome.
- Reinstall only through metamask.io or the official Chrome Web Store listing.
- Confirm the publisher and extension identity.
- Choose the restore or import option for an existing wallet; do not accidentally create a new wallet.
- Verify the expected addresses and balances before sending funds.
- Reconnect dapps individually and review each permission request.
Do not manually downgrade MetaMask or install an older package. MetaMask says reverting to an earlier or custom Chrome version is not recommended unless directed by a developer or MetaMask Support.

If Chrome says MetaMask is corrupted or disabled
- Open
chrome://extensionsand read the exact error. - Update Chrome and restart it.
- Check whether Chrome disabled the extension after an update.
- Determine whether the computer is managed by an employer, school, or administrator.
- Test a personal Chrome profile or personal device if permitted.
Managed-device policies can restrict extension installation or require administrator involvement. Do not replace MetaMask with a similarly named extension found through an unfamiliar site.
When the issue involves Ledger, Trezor, or another hardware wallet
A hardware-wallet connection failure can look like a MetaMask crash but may be a separate problem. Check the device firmware, relevant wallet app, browser version, USB connection, device lock state, and whether the correct blockchain app is open. Also check whether companion software must be closed for the connection to work.
Test a normal software account if possible. If MetaMask works with that account but fails only during hardware-wallet actions, focus on the device and connection layer. MetaMask’s current compatibility instructions are in its Ledger and Trezor guide and hardware-wallet hub. Compatibility varies by device, browser, extension version, and platform.

When to contact MetaMask Support
Contact MetaMask through its official support route if the crash continues after the safe escalation steps, especially if it began after a specific update or affects multiple profiles and supported browsers. Record:
- Your operating system and version.
- Chrome version and MetaMask version.
- Whether the popup, full-page view, or dapp connection fails.
- Whether all accounts are affected.
- When the issue began and whether it followed an update.
- Whether disabling other extensions or using a fresh profile helped.
- The exact error message.
- A screenshot with recovery phrases, private keys, passwords, QR codes, and sensitive account information hidden.
Provide console errors only if official support requests them. Never disclose your Secret Recovery Phrase or private keys to support.
