Yeah, unfortunately, it just isn't possible to have two different versions of MetaMask installed right now, even if one is a forked version, and we don't have plans to support this any time soon. If there's some improvements you'd like to make to MetaMask, however, feel free to submit them to our [extension repo](https://github.com/MetaMask/metamask-extension). Or, if you're testing our your forked version, you can simply go to your Extensions page (chrome://extensions in Chrome, about://addons in Firefox) and disable the official version of MetaMask instead of having to outright uninstall it. Hope that helps.
