Nice Rated 4 out of 5 stars
I think this is a great add-on, though it would benefit immensely if the whitelisting feature was able to either
a.) support wildcarding
b.) allow you to enter a domain and all subdomains on this domain will also be whitelisted
It's a little inconvenient (just an example) to have to whitelist www.google.com, as well as mail.google.com - being able to input "google.com" or "*.google.com" would much improve that system.
Thanks for the suggestion. You're not the first one to bring it up. It's definitely on the list and I might do it, but only if it doesn't make the already pretty complicated preference window not *more* complicated.
