What you're doing with Little Snitch is essentially what basic adblock does (under Preferences, TenFourFox). If you have suggestions for specific hosts, you can see the current list in the source in Github. By policy we don't block hosts that provide what we consider to be core site functionality, so a combination can still be useful.
Because of the complexities involved we do not accept donations, but thank you for offering. If you like, visit the TenFourFox Development blog and click on the advertisers. http://tenfourfox.blogspot.com/
