Revert back to earlier version, or add custom build to Chrome

This is fairly advanced functionality, and isn't something you're likely to need to do unless you're a software developer, or unless a Support agent is directing you to do so. Proceed with caution.

Previous versions of MetaMask can be found here.

• Open Settings > Extensions.
• Alternatively, use the URL chrome://extensions/ in your address bar
• Check "Developer mode" in the upper right-hand corner.

• At the top, click Load Unpacked.
• Navigate to your custom or previous version metamask-plugin/dist/chrome folder.
• Click Select.

• Change to your locale via chrome://settings/languages
• Restart the browser and test the plugin in your locale

You now have the plugin, and can click 'inspect views: background plugin' to view its dev console.

Instructions for Firefox and Opera can be found here.
