Firefox and Chrome don&#x27;t do &quot;move fast and break things&quot;-style continuous deployment, can&#x27;t push updates to a user seamlessly (i.e. without restarting the program), and can be downloaded and compiled on platforms that Mozilla and Google don&#x27;t want to officially support.<p>Native delivery of a monolithic browser based on an open-source codebase is a fixed problem. Trying to do the same with a website, using current techniques, would cause issues to both their current workflow and my expectations as a user that websites don&#x27;t currently have.<p>I&#x27;m not saying that it&#x27;s impossible to do, I&#x27;m just saying that it&#x27;s not a good fit for current trends in web development, and I&#x27;m not convinced that it would be great for the users either.
