I know this post is a bit older at this point, but do you have any custom fonts installed? I could reliably reproduce my browser fingerprint as you described, even between Librewolf and Firefox with different configurations (including JavaScript disabled in Librewolf). A visit on one browser would increment the counter, and vice-versa.
I had forgotten that, quite some time ago, I’d installed a font not packaged with my OS - I deleted it, made sure to clear out my site data, changed IPs, and finally got a shiny new fingerprint.
Cross-referencing with EFF’s coveryourtracks site, I also noticed that one metric that almost never changes for me is my audiocontext fingerprint, although I can thwart that by disabling JavaScript, but maybe that’s contributing as well?


I think we can skip the “loving” part and leave the rest…
