Question: Does anyone know what security and privacy extensions are considered redundant in light of recent Firefox improvements in the past few years?

For example, I saw several people recommend Privacy Badger for example. I thought I heard somewhere that was considered not needed now. I do not know for sure so am frankly confused by this and some of the other extensions which I too use to use.

For me I have kind of stopped using most security/privacy extensions except uBlockOrigin and then just configuring Firefox rather tightly. Not sure if this is best approach or not. On one hand every extension increases the attack surface and the uniqueness of the browser so there is a point about less is better, on the other hand some may be useful too.

Thoughts? Thanks.
