As you suggested, I suspect it's the rare combination of additional extensions that's contributing to your uniqueness in a fingerprinting sense.

Firefox's built in "Enhanced Tracking Protection" already does a lot of this work for you, especially if you select "strict mode." Go ahead and try this extension if you prefer. But remember to be selective with the extensions you add to your browser in general, as they also present an opportunity to introduce vulnerabilities.
I never knew anybody who used it. I had one contact on ICQ. Everybody else used AIM.
Tildes fits that description. The posts are text-only or links to websites. No memes.

Yes, SELinux is enabled (in "enforcing" mode) by default in Fedora. In my experience, it doesn't hamper usability.
I remember seeing old advice from blogs and listicles about turning it off, on the theory that it might get in the way. But it's better to leave it on if you care about security -- especially if you want to learn.
When SELinux blocks a piece of software from doing something sketchy, an alert is generated to explain what happened and why. That's rare but it's a learning opportunity for you, not to mention preventing a potential security threat.
I'd rather see a photo of the set, after you build it, than a photo of a box.
