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.
Built in browsers in apps don’t have them.

I’m using that now.
Or you can just turn in-app browsers off.
Depends on which browser is the default, I think. Even if that doesn’t work you can set you private DNS and block most things though.
