Fingerprint.com allows you to test web fingerprinting. This is a more advanced method of tracking individuals throughout the web without the need of cookies.
Mozilla The Tor Project developed a pretty effective toll tool against this called resistFingerprinting. It can be enabled in about:config. LibreWolf has this feature enabled by default. Sadly, it doesn't really work.
On Firefox you can visit fingerprint.com in a private window with resistFingerprinting enabled and after closing the private window and visiting fingerprint.com again, there will be a new id meaning that you have not been tracked.
On LibreWolf you can do the exact same thing but the same id will show up every time. Is there a way to configure LibreWolf to be more effective at resisting fingerprinting?
On LibreWolf you can do the exact same thing but the same id will show up everytime. To get the same functionality as Firefox you need to install the Canvas Blocker extension.

These tests are not intended to be used as oracles, but rather as a way to check your setup and verify that your changes are applied. You should not read too much into the results unless you are sure you understand them, as explained in this article.

BTW I commented about this in the past, see https://gitlab.com/librewolf-community/browser/windows/-/issues/276#note_1137125815
