Those addons are very basic, just what I'd have done in 2010 --- before Snowden!
Since you have Firefox, you could sync with a community-developed user.js like Arkenfox (previously GHacks) [1], which seems to go much farther and still not break much! At least the settings privacy.resistFingerprinting and privacy.firstparty.isolate looked indispensable as soon as I learned what they do.
And without FPI (first party isolation), not getting LocalCDN [2] (Decentraleyes successor) and Temporary Containers [3] seems like a gross oversight. They have a great discussion on add-ons at the Arkenfox wiki [4].
