No, xulrunner wasn't forked and the firefox package in Fedora uses the
system xulrunner. In the case of the repo with FF4 there's a
xulrunner2 package and all the libraries and names of the package when
built have been changed. To use it you have to change the way the
xulrunner app links to which version/name of the underlying xulrunner.

No idea about windows nor thunderbird but firefox 3.x and 4 will both
use the same profile (I was switching between the two for a while when
FF4 had issues even restoring the sessions) and use system proxies.
