Did you receive the update automatically, or did you download and install it manually? If you are using automatic updates, Firefox should ask before updating if any of your add-ons will be disabled.
My experience is that if I click "Check for updates" and an update happens to be available, then there's no way to prevent that update from being installed, even if it causes add-ons to be disabled.
