'Morning Frank,

What addons (if any) have you installed in Firefox? I've been using Firebug for development purposes, and since disabling it for the UT I haven't seen the problem since (crossing fingers, knocking on wood, etc.) Another method I tried was to install Fiddler and set Firefox to use an auto proxy configuration script through Fiddler to see what the problem really is. I could not get Firefox to fail in that configuration.
