The only way I've found to ensure this doesn't happen is to set about:config -> network.http.use_cache = false.

Private browsing keeps it for at least one restart (with clear everything set in options), even though I can't see tracker.jpg in about:cache anywhere. Other weird thing is tracker.jpg isn't showing up in a filesystem search anywhere. Wondering if there's something stored in the sqllite files.

That works, thanks!
