I-Firefox Isithangami Sokwesekwa

I've had Firefox "armored" for a while - Ublock to block adds, Ghostery to block trackers and other things, Cookiebro to control who installs information on my computer. The latest Firefox (63.0) now also has tracking protection. I've mostly been happy with the first three - is Firefox's new tracking protection overkill?? Maybe too much of a good thing, and if so which one should I get rid of??

Any suggestions? thnx,...

Suppose i want to access 123newss.com, which uses technology from t.com I create a ublock "global-filter" of the domain t.com, that blocks loading of t.com at 123newss.com and everywhere else. For some reason i'm a frequent user of t.com, and whenever i try to visit t.com i have to temporary unblock the blocking of t.com. This creates a lot of friction since i'm a frequent user of this url. If i create a ublock/whitelist of domain t.com then ublock allows every tracker to load at t.com, eg. t.com visit triggers loading of 21trackers.com.

The idea is - Block tracking urls globally, but allow auto whitelisting of urls when visited directly. Analogy: prevent embedded yt videos from loading in arbitrary website, but allow when you have visited 125yt.com, without also allowing every other 21trackers.com domains at 125yt.com from loading. Sounds like containerization or "cross-site" url loading block. Is it possible or am i missing something?
