[Feature request] Let other apps share URLs to have them opened in app

[pzmarzly]

E.g. I'm browsing some story on fanfiction.net in browser, I hit Share->Open in FF Reader, I have the same story opened in app.

Right now app registers as URL handler for {www,m}.fanfiction.net, but URL handling on Android is crappy (how do I trigger handler inside Chrome?). User can install Open in Browser tool, but some apps register as a sharing utility by default (e.g. NewPipe (Youtube client), Comfort Reader)
