similar, i used Random User Agent, it shows that i have a unique finger print... but the user agent of that fingerprint is not 'my' user agent, so in 30 mintutes i would appear as a different fingerprint
In my experience, you have thee choices. You can use NoScript and avoid enabling domains required for fingerprinting, you can turn on privacy.resistFingerprinting in about:config, or instead of focusing on not being fingerprinted, focus on guaranteeing your fingerprint will keep changing.
Be aware that any sites using HTML5 Canvas will probably be broken now. It breaks some other niche things too that may not be obviously related, so just keep that in mind if any site starts acting up.
