Is there an extension for desktop that does it? Install it on the mobile version. New (chrome) style extension just work, from what I know (there are a few APIs that don't, but those that use them are likely the extensions that don't make sense on mobile). An extension I made for work just worked without problem. Edit: Sorry, I was referring to Firefox mobile, and this is regarding Firefox preview, which I don't have any actual experience with. I'm not sure how much applies.
