I love how you&#x27;re talking about the process from a user point of view. This is truly a difficult time for Mozilla. The rise of iOS means that independent renderers have not as much of a voice as they could have. It is scary because a user will maybe rely on features that exist on Firefox on another os might not work on Firefox on iOS.<p>The renderer is still very critical for developers. We don&#x27;t really have a browser without a renderer after all.
