On iOS, yes. My understanding is that Apple forbids installing full Safari alternatives on iOS. On iOS the only permitted browsers are Safari reskins that use the Safari webkit. Source: https://en.wikipedia.org/wiki/Firefox_for_iOS
If I'm misinformed please let me know.
This greatly impacts ALL web development. Many people use iOS, and Apple prevents the installation of real alternative browsers. As a result, it's typically financial suicide for any web developer to use a client-side feature not currently supported by iOS Safari.
There is one partial exception: Puffin. It uses Chrome on Linux and a custom lightweight remote desktop-like client to let the server render the pages and the phone view them.
It's an impressive work around, though it adds it's own problems, not the least of which putting a lot of trust in a third party.
