# Firefox popup blocker filtering exceptions

firefoxpopups

This might be a dumb question but what exactly is the filter rule format to globally allow sites? Do I need multiple entries to handle folder structure of the sites and entries to handle subdomains? Is an asterisk used for a wildcard, do I even need to use a wildcard?

• To globally allow a site, just add their base url:

example.com    Allow


If you just want a subdomain of a site, say their webmail client for exmaple:

webmail.example.com    Allow


You cannot specifiy a certain directory or page to allow, pop-up rules are all based on the site.
