UriSchemes/chrome
In .mozilla/connolly/4evx0poc.slt/localstore.rdf
I found:
<?xml version="1.0"?> <RDF:RDF xmlns:NS2="http://home.netscape.com/WEB-rdf#" xmlns:NC="http://home.netscape.com/NC-rdf#" xmlns:RDF="http://www.w3.org/1999/02/22-rdf-syntax-ns#"> <RDF:Description about="chrome://messenger/content/SearchDialog.xul#priorityCol" ordinal="19" />
What is chrome:? Where are the docs?
Now I remember a reason why not create new UriSchemes: you can't FollowYourNose to look them up.
