1. for debugging minified JS we tried to use source maps, but they were not supported (I have to say that Chrome claims to support it but it is working intermittently). So our fallback today is to serve non-minified to developers (based on a cookie) and minified to the rest of the world. The drawback is that users may report JS exceptions with the line numbers which are different from what developers would see.
2. for mobile I need FF to let my webaps compete with native apps. Mozilla is changing the game on mobile with webapis to devices https://wiki.mozilla.org/WebAPI, you guys are the saviors! We have been waiting for the ability to write device interfacing webapps since 2008! Our team is on the way with an MVC framework that utilizes device webapis, see http://github.com/urbien/urbini. But one critical thing is missing - Firefox needs to start as a service on device boot, and webapps should be able to register JS callbacks in this service. It does not need to include a rendering engine, but webapp should be able to spawn full browser. Without this we can't write proximity-based social apps, a bump-like app for business cards, network aware db sync engine, etc. To continue this line of thinking, it is not always devices that you need your webapp to communicate with. Sometimes it is Android intents. Like the intents defined by pebble watch service http://developer.getpebble.com/
What would be cool is to have a generic interface to those intents in Javascript. I know it is Android-specific, and iOS will need another solution. The idea I want to throw on a table is to define any interactions with native code as Models in MVC. Our team is prototyping such for Pebble smart watch right now http://urbien.com/app/Pebble. I am available for brainstorming if you want to take it further.
