I don't get anything but a blank screen from entering about:config as advised on another website....still trying to enable Javascript to use for petsmart.com shopping for dog food. Not a huge problem but I would like to fix it. Keyword searching in Firefox settings and FAQs for "Javascript" doesn't get anything helpful so far. About:config is an "insecure" connection on my phone. Could it be Norton causing this problem? [Email address]
