I have been trying to make a Safari Extension the last days, and I have to say that this is a nightmarish and unpredictable experience.I have launched the app first to register with Safari. The extension then shows up in my regular Safari extension and it seems quite stable, but debugging doesn't work.When I launch the extension and run Safari, a new instance is started, so I then have to enable unsigned extensions every time I make a change. The plugin is often not injected. And if it is, it crashes shortly after.There is no feedback on why any of this hapens.Am I doing something wrong, am I just unlucky, or is this part of OS X development simply not ready for developers?
