&gt; It should&#x27;ve been supported directly within the Firefox chrome ASAP.<p>That could have been fixed, and could still be fixed.<p>&gt; It had branding different than the site you logged in to and was in a popup[1].<p>That could have been fixed, and could still be fixed.<p>&gt; It took the name of another Firefox feature that users already knew about.<p>That could have been fixed, and could still be fixed really, but it&#x27;s pointless now.<p>&gt; Because the team was experimenting fast, the code quality of the service was such that outside contribution to it (or even cross-team contribution internally) was hard to impossible.<p>That could have been fixed, and could still be fixed.<p>&gt; We had enough time to do these things, but we didn&#x27;t. The team accomplished something really amazing, but it wasn&#x27;t enough, and most importantly, <i>putting more effort into what already existed was not going to work.</i> This idea that Mozilla can just turn around and throw effort at Persona and make it win now is, IMO, wrong.<p>Why wouldn&#x27;t it make it work? Persona was only alive for 2 years. It saw slow adoption, in part due to usability issues. If you fix the usability issues and give it more time, why wouldn&#x27;t it be more successful? The issues holding it back were not fundamental. In fact, the fundamental design of Persona was sound and worked very well.<p>Now, yes, merely fixing things and making the project supported again won&#x27;t make it more successful overnight. It may need rebranding, it may need a lot of promotion, strategic partnerships, etc. But to declare it completely dead and waste effort on recreating <i>what you already have</i> is silly and counterproductive.<p>Persona already has many sites - and people! - using it. It already has some (limited) brand recognition. It already has a solid protocol and design, a working codebase, a hosted service that is usable.<p>The hypothetical successor to Persona? It has none of this. A hypothetical new approach? It has none of this. Could that change? Sure, but you&#x27;re still starting from zero, and you have to re-do everything.<p>But why start again when what you had wasn&#x27;t fundamentally broken?<p>&gt; We need a successor or a new project.<p>Why? What could a successor or new project bring that Persona couldn&#x27;t?
