I think that is correct, but it still seems like an amount of leakage that could be further correlated with other another trick.

There was previously a site which could indicate how globally unique your environment was (some combination of screen size, user-agent, fonts?, etc). Locking down to a specific hardware+browser configuration probably does a lot to remove anonymity.

Not the one I used, but this one actually looks better.

Just being Linux + Firefox is terrible for blending into the herd. Let alone everything else that leaks (having a desktop + GPU + good monitor basically destroys all remaining hope).
