As a privacy-concerned user, I try to make sure that Google, Facebook and the like do not get informed of whatever page I visit through web bug like Google Analytics and the Facebook "I like" button. Thus I block them using a combination of Ghostery and AdBlock Plus on Firefox.
However, jQuery is another script that gets often downloaded from Google's CDN, and I cannot blindly block it since it is needed by other (beneficial) scripts. So, question:
Is there a way to block downloading jQuery from Google's CDN without losing completely its functionality? The ideal would be replacing it with a locally-hosted copy (well, several, depending on the needed version), or one hosted on a server of my choice. Is there any privacy tool offering this functionality without much tweaking?
