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:    Allow

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

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

Does also cover, ? – Chris Marisic Jul 22 '09 at 13:13
Yes, will cover whereas covers just (~ meant to be a star, but the editor seems to eat asterisks) – heavyd Jul 22 '09 at 13:25
@heavyd, you need to escape your asterisks: * – nik Jul 22 '09 at 13:41
It would've been nice for their website to make it clear about subdomains / implicit wild card usage. – Chris Marisic Jul 22 '09 at 13:51
* does not allow – Felipe Alvarez Dec 31 '15 at 0:21

This Mozilla Support page for Pop-up Blocker should be useful.

Rules are simple -- like heavyd has already described.

If you want to go beyond that in firefox, you should install the
AdBlock Plus and maybe NoScript extensions.
AdBlock Plus will give you lots of flexibility.
