Ionic2 - Pretty URLS (eg remove hash#) - Ionic / Firebase experts only please

I have simple 3 page Ionic2 web app (home > detail > detail). I have setup it up to use custom back link URLs, which work fine. but have a # eg [login to view URL] I need someone to tweak the code so that it works correctly using the "path" setting so the URLs appear like this: [login to view URL] I think this will require a code tweak and some rewrite rules for the hosting (I want to use Firebase hosting). This should hopefully be easy for an Ionic/Firebase expert. The winning bidder will be used for future work.
