Neat, is there something like this for FF as well?

Not that I know of sadly. There's an open issue, but no progress as far as I could see. I haven't tried, but technically Firefox should support the WebExtensions APIs that Chrome uses, so it might be worth trying to manually load in the Chrome extension into Firefox.
