I have no idea if this works iPhones because Apple pretty restrictive (Do they allow anyone to use anything other than Safari or are they still on that anti-consumer kick), but on Android you can set the browser engine the in-app browsers use. So you can set it to Firefox and then have plugins.
I’m using that now.
Or you can just turn in-app browsers off.
