User reviews
I use this with custom settings (see below) in combination with CanvasBlocker to make my browser extremely resistant to fingerprinting well maintaining web functionality. I also highly recommend using LocalCDN to reduce tracking. Check out the add-on CloudHole by scakemyer if CloudFlare is a issue or your running a VPN but I usually have no issues.

Extremely complex but the only working fingerprint spoofing extension out there now that the original Fingerprint Spoofing extension/add-on has been removed from Github because later reiterations are malware and developer has stopped supporting it more than 5 years ago. On Firefox, but not Chrome it ramps up CPU usage and RAM.
