This question already has an answer here:

with uMatrix I can block domains for specific external content. But I would like to know if there is also a blocker for specific scripts on a domain. With uMatrix it is all or nothing for one source type (image, css, script, ...) for one domain, but I would like to allow some scripts and block other ones on a single domain.
