I'm having an increasingly annoying problem with Safari on my MacBook. For various reasons, I like to have Firefox as my default browser and have selected it as such in Safari preferences. However, following each reboot, I find that Safari has become the default browser. The problem has persisted through the last couple of updates to Safari and Leopard and I am currently running the latest versions of both (3.1 and 10.5.2, respectively). I've tried deleting various preference files to no avail; I suspect that the problem is related to a botched migration to Leopard, but I've already reinstalled once and would really like to avoid doing so again if somebody knows of a simple fix. Anybody know where my default browser settings are hiding? Help much appreciated.
