Cause: When you install the MetaMask plugin, it is connected to a test network and can't get your account balances.
-
Solution: Connect MetaMask to the Ethereum Main Net so it can get your real account balances.
-
Instructions: Click the test network at the top of the plugin window and select Ethereum Main Net from the list that appears.
This action logs you out of MetaMask. When you log back into MetaMask with your password, MetaMask shows the correct account balances.
Q: I can't use the import feature for uploading a JSON file! The window keeps closing when I try to select a file!
- Cause: This is a known bug in Google Chrome that appears in Ubuntu and some Windows builds.
- Solution: A good workaround is to open the extension url, chrome-extension://nkbihfbeogaeaoehlefnkodbefgpgknn/popup.html, directly in a new tab and import through the tab.
