The only thing I would like to do is block certain trackers manually. For example "geoplugin.com" is enabled by default in Disconnect while I can block it manually in Ghostery. And I became used to not seeing google +1's and tumblr share buttons etc. Isn't there the possibilty to block them even before I visit a page? Right now I need to disable them via the disconnect UI and the page needs to reload.
