How to Install MetaMask on Firefox Today
Mozilla hand-reviews every Extension submission, and at time of writing, we’re in line position 332 of 645, so Firefox support is coming, but if you’re impatient, and don’t mind voiding your browser’s warranty, there’s no reason you can’t use MetaMask with Firefox today!
Developer Edition Required
Mozilla has a special version of Firefox that doesn’t require their approval to add extensions, so you’ll need the Firefox Developer Edition.
Once you’re running Developer Edition, you’re going to need to visit the config page at
about:config. This will give you a big scary warning that this may void your warranty, and it may! So heed it!
You then want to find the setting called
xpinstall.signatures.required and double click it to say
Go Download MetaMask!
Our link on the Firefox store is here, and you can now use it!
Normal Firefox users will be able to use that link once we’ve been approved & signed by Mozilla.
