This is a feature request, not a bug. Basically, spoof the timezone and locale if the user is on a VPN. @bsclifton could we do this if the user is on Brave VPN i.e. use the chosen VPN server's location to report the timezone/locale

Randomize them i have given examples. I randomized spoofed the timezone/locale related fingerprinting on kiwi android browser using chrome extensions and tested them through browserleaks testing. And they were success

This will enhance the privacy websites and trackers wont be able to know location. (Location are also important factor that marketting companies using to commercialized their products depending on which region users has searched more for products)
