Hardend Firefox in incognito or just Librewolf with uBlock Origin, Privacy Badger, and Decentraleyes add-ons along with Mullvad + NextDNS is the best combination. If you can also have pi-hole it can also do a good job at blocking trackers..NextDNS seems to do the job for me though. I use Mull browser on android.
Privacy Badger, doenst bring anything to the table that uBO cant/doenst cover and having mutliple adblockers installed might even make the result unpretictable (the arkenfox wiki, explains that pretty well)
Also Decentraleyes is outdated but there is the active fork https://addons.mozilla.org/firefox/addon/localcdn-fork-of-decentraleyes/
Hope these infos help or are at least a bit interesting.
No, you're not a bother at all; this is very informative! I don't personally have the time to delve into the technicalities of why something may be outdated or maybe even redundant. I just kind of follow what has worked for me, as I want to be as anonymous as I can be while browsing the web. Furthermore, I will change Decentraleyes out for LocalCDN; I appreciate this tip.
