We recommend Brave. Brave has had their problems but you can disable all those things just fine. Spoofing your timezone is not going to stop fingerprinting that is a fairy tale. If that is your thread model you should seek other methods.
Well, it at least reduces the fingerprinting (I think) to a certain degree. A person browsing the internet with different IP addresses but the same Timezone will be easier to fingerprint than a person browsing the Internet with different IP addresses and Timezone complimenting those IP’s.
But, you are correct that these two will not defeat fingerprinting, however they can at least somewhat reduce it.
Sorry it really does not. It’s just one attribute and it will not make a difference really. Using a less used browser like Mulch will likely only make you more unique than using Brave with your timezone.
