on osx 4.11, FIREFOX automatically installs updates, then announces this update is incompatible with my OS.

I do not want or approve of IMPOSED-INVOLUNTARY updates. How can I PREVENT THEM IN FUTURE ? There is no feature in preferences to allow me to reject updates ! This is very tyrannical of Firefox.

Firefox 3.6.x (Mac OS X 10.4 and later) can be found here:
