update 2:
http://kmext.sourceforge.net/files/famfilterproxy2.7z
this update enables adding and removing custom domains to the pac
add a domain[filtering can be done in 2 ways.
quic block, by right clicking on a page and selecting famfilter blocker
the domain is blocked instantly and page is refreshed(no need for restart)
foolproof: in case adding an existing domain
other method is through a config dialogue: select tools>proxy>familyfilter config
the dialog will open and automatically add the page domain, you can edit it to add custom domains
footproof:in case adding an existing domain a message will be displayed
foolproof:adding an invalid address
to unblock a domain, select it from the combobox and click the unblock button
the combo will be refreshed removing it from the list
will also be refreshed when adding a domain and displays it in the list aswell
when there are no custom blocked domains, the combon and unblock button will become disabled
please note, good domains and ip range take precedence over bad domains..famfilter is content filtering proxy and should not be used to block good websites, you might block a good website like news etc and dind that it can still be accessed through famfilter..this isn't a bug but smart filtering ensuring domains in the good range can still be opened and browsing speed is unaffected unlike other filtering that check everything and slows browsing with normal websites that should not be checked
