None of these extensions will fix the subject of this thread though. The problem is that at some point Nokia decided to put the whole FF-derived browser into a daemon, difficult to kill if it fails and using gobs of shared memory for communicating with clients. Given the sheer size of the engine and its complexity (read: propensity to failure), making it resident does not seem to be such a good idea, especially if all it does is shaving 2 seconds off the startup time.

I would say, make it optional, the same way Python Launcher works.
