It's definitely a difficult transition time for Mozilla/Firefox, and I think they're struggling to find their footing. I'm not sure if all the decisions they are making are correct, but as time goes on I think their plans are coming together more. i Plugin incompatibility is a problem at the moment, but they have systems in place to help mitigate it. If they can manage to keep it temporary, I think they can survive.

I don't have much experience with the new extension SDK, so I can't comment on it authoritatively. The old system is not without problems, and I'm actually glad that they are moving over to something closer to Chrome in terms of certain things...
