uMatrix + NoScript personally (yes, seems silly, but I find NoScript's UI more convenient for script toggling, while liking uMatrix's fine grained controls)
Did you enable firefox resist fingerprinting?
Also maybe letterboxing, which I think is not enabled by that flag by default, and also helps with CSS fingerprinting.
It hasn't received updates in a good long while, but seems to work fine, for me anyway. Has some rough edges, logging blocks when there's a bunch of redirects is a bit of a pain, making it hard to fix whitelisting in complicated things (like the dozen domains microsoft uses for auth) but apart from that...
(and ofc there's a bunch of forks adding bugfixes, some even relatively recent in activity, but unfortunately none have become the blessed official maintainer)
Did you specifically re-enable javascript? Ublock origin on medium mode blocks all the tracking javascript and I'd think advanced would follow the same basic starting point.
