would be trivial to bundle the signer i created, plebeian signer, into a lightly customised build of librewolf and i made a fork of the only android fork of firefox that allows extensions, that i called felice, include ublock origin as well. my extension has NWC for lightning and implements nip-60 and nip-61 cashu wallet. the rest of the features, share to nostr, translate page, highlights and comments on external websites i think someone made a nostr app that does that, just needs an extension integration (might already exist). so long story short, it is mostly just a custom bundling, can be done right now with librewolf and fenix or whatever it is called. anyway, my felice version is better because it disables the mozilla signing security theatre. you can just install whatever on it. the main things are finding the features you want and the nostr apps that integrate with them.
