The MetaMask Firefox extension is a few versions ahead of the Chrome extension. The Firefox one doesn't work anymore due to the breaking changes in MetaMask regarding no longer injecting web3, more info here. When trying to fix the issue, it seems there was very little to do actually to my surprise. Mainly a few undefined-guards and one location that I should have used Utils for anyways.
