So checked the console in Firefox and got `SyntaxError: invalid regexp group` errors.

Turns out Firefox doesn’t supported [named capture groups](https://github.com/tc39/proposal-regexp-named-groups) for regular expressions:

Going to mark Firefox as unsupported, however seems they are working on it - perhaps will land by the end of the year looking at current progress on their side.

Will update the readmes accordingly, thanks for the heads up!
