As I said, only in the manual rext entry rules in settings.

In uMatrix that's one click in the appropriate column per domain's row, in the toolbar drop-down.

Scripts, image and frames can be blocked with one click in ublock too.

One and not the others?

My uMatrix default is all cookies blocked; third-party media, scripts, XHR, frames, other blocked. Of course I often then have to allow some third-party script, and I can do so in one click without also allowing XHR or frames to/from that domain.

uBO doesn't allow that (in the toolbar UI, 'advanced'/'more' mode), because it's missing the columns from the 'matrix', so you either allow/block a domain wholesale.
