security.fileuri.strict_origin_policy = false
But now we're porting to Linux and I'm upgrading to xulrunner1928 on RedHat Linux and I'm getting script denial errors:
script from file:// was denied UniversalXPConnect privileges
Any ideas of where to start looking? I can see xpconnect/chrome.manifest changes with gecko2.0, but I don't think I should have to do those upgrades since I'm still working with xulrunner 188.8.131.52.
