Yes, but beware that many websites are broken when “resistFingerprinting” is enabled. That’s why that mode is not enabled by default or an opt-in option in Firefox’s settings UI.

I've ran into a couple ones that have some canvas-based features that break when resistFingerprinting is on. They get some visible noise added on top (which does indeed thwart fingerprinting, but also makes it harder / weirder to use those features).

I believe you can turn off the canvas-based meddling per-site. There's a small icon that appears on the left of the URL input box on affected sites that allows you to do this.
