why does Firefox pretend to be using resources on a removable drive when it isn't?
Frequently, and on more than one Macintosh computer, I have a portable drive connected that I take home with me at the end of the day. It doesn't matter whether it's connected via USB or Firewire, if FireFox is running, I cannot unmount the drive until I quit Firefox. No other browsers that may be running behave this way.

I don't use Font Book; I use FontExplorer X Pro. Deactivating fonts just to make the browser happy is not an option - I do graphic design. And there are NO fonts being referenced on the portable drive, unless FireFox has some wild capability to do so on its own.
I have set my fonts up very carefully within the system and this should not be an issue.
