I use uBlock Origin and make some changes to the default settings. Have seen recommend configs, but haven’t gotten to implement them yet.
What do you do to make Firefox even more privacy respecting and secure?
Really shouldn’t use anything more than uBo since extensions make it easier to fingerprint you.
This is absolutely false. In a standard browser environment you are going to require a multitude of plugins to achieve various tasks. In fact; having uBo installed is in and of itself fingerprintable to the nth degree. An advanced fingerprinting suite can glean data from your browser based on which uBo lists you subscribe to.
With the sole exception being purpose-hardened browsers like Mullvad’s or Tor Browser; there is no reason to skip having plugins. You already fingerprinted yourself by running that one plugin.
