Doc improvements

[nagkumar]

The FirebaseUI component implements best practices for authentication on mobile devices and websites,

This info is not very clear, if it supports mobile browsers too and if the firebaseui-web is reactive enough to work on all devices including tablets, tvs, watches etc...

can you pl. improve the documentation, also, it would be nice to put in the UI shown display reactive UI serving xyz device that it is displaying on

Thank you for taking the time to submit this feature request

This is a great idea and definitely something we can consider for the future. It is not currently prioritized for our immediate new version roadmap, as we are focusing on a new upcoming release.

In the meantime, we will keep this issue open so we can revisit it during a later planning cycle, particularly as we gather more feedback from the community.
