In builds since last night, if you open the prefs panel, and just view any panel that contains a textfield, and then click OK to close the dialog, then the preference values for the textfields will be overwritten with blank or zero values.This can affect things such as disabling disk and network cache, disabling history and persistent cookies (I think), setting the browser to use HTTP/1.0, and other effects.
