In the long run it will be more and more important to do some active 
spoofing, too. I rapidly get to diminishing returns after doing the 
privacy basics (remove unnecessary mobile apps, use a browser with 
uBlock Origin for as much as possible...)

No, I'm not seeing a toolbar in that browser.

I have tried a bunch of the preferences and still getting some of those 
browser DNS lookups. For now I guess I'll just check a couple of blank 
pages first and disregard anything that Firefox looked up. (But it will 
be interesting in the long run to see if any sites are using 
`ads.mozilla.org (mozilla.map.fastly.net)` for anything.)

And as soon as big money is involved in having AI running on your
browser, it'll get harder to remove that, too.

Just look at the Firefox privacy versions.  All the real privacy
browsing is not simply reconfiguring Firefox, but a separate version
compiled by someone else.</pre>

Do you have the toolbar with links (as buttons) on it showing?  I would
imagine that for every button, it would be doing a look-up to at least
find the lastest favicon for the link.  You'd want to switch off the
