A view week ago, I had a nasty problem. I updated my xulrunner installation to 7.0. A software project based on xulrunner wouldn’t run with this version. Ok, back to the old one. But how? The installer of the new hasn’t any uninstall option and the installer of the old one was canceling, because a newer version exists.
Googleing around I’ve found a few hints but none of them works correctly or wasn’t the half line.
To delete the whole xulrunner manually you have to delete the following items:
/private/var/db/receipts/org.mozilla.xulrunner.bom(seems relevant to 10.6.7)
/private/var/db/receipts/org.mozilla.xulrunner.plist(seems relevant to 10.6.7)
