Off the top of my head, no. What I do remember is that I couldn’t use Librewolf as my daily browser because I had trouble using every other website. Might be an exaggeration, and it could have been due to other factors, not just resisting fingerprinting.

I’ve just come across this article: https://kevinboone.me/fingerprinting.html

The author describes the situation pretty well:

you enable fingerprinting resistance in Firefox, or use Librewolf, you’ll immediately encounter oddities. Most obviously, every time you open a new browser window, it will be the same size. Resizing the window may have odd results, as the browser will try to constrain certain screen elements to common size multiples. In addition, you won’t be able to change the theme.

You’ll probably find yourself facing more ‘CAPTCHA’ and similar identity challenges, because your browser will be unknown to the server. Websites don’t do this out of spite: hacking and fraud are rife on the Internet, and the operators of web-based services are rightly paranoid about client behaviour.

You’ll likely find that some websites just don’t work properly, in many small ways: wrong colours, misplaced text, that kind of thing. I’ve found these issues to be irritations rather than show-stoppers, but you might discover otherwise.

It could be done on the browser level (maybe it’s something browsers like LibreWolf do), however, it would break sites that require the fingerprints to be the same for “security reasons” which may or may not be a legitimate claim.

You could say “well, I’m not going to use that particular website then”, but the problem is that there are less and less websites that don’t require these technologies to function properly.

In case you are willing to use the beta version of the app: if I remember correctly it’s available in beta.
