This extension is extremely useful and the developer is a really nice person and cares about potential bugs being reported.

Works so good, that some websites do misbehave:
If you ever encounter the issue that dates you select are changed, or that some time-scaled maps dont show the data as expected, deactivate the addon and see it was the spoofed time-data that caused this behaviour :)

I love this Addon! Thank you!

Addon works as supposed, spoofs the timezone. But it works too aggresively leading some of the websites and services to hang and crash.

Using it for development/testing. Perfect

The "Pick a random time zone" button is exactly what I was looking for with an extension like this.

tested works fine

doesn't work

it spoils local (lan) sites. must have exception list.

работает, но времяные зоны меняются не автоматически.
P.S.: он меняет зоны в зависимости от вашего ip

does NOT spoof timezone

Автоматической смены пояса, или хотя бы по клику, нет. Надо переться на сайт проверки IP, потом в настройки, причем несколькими кликами, и менять вручную.

for me it opens a looping captcha when toggled, nothing else happens

It technically does what it's supposed to do but has 2 major flaws: 1. it immediately opens a page proxied with Cloudflare which asks for me to enable JavaScript and centralizes the web 2. not having an allow list is very limiting--for privacy and resistFingerprinting users will want UTC as the default, but allowing a few websites through like an email client would make it usable without sacrificing the entire browser's state.

Has all the options I need and works flawlessly, perfect for avoiding fingerprinting.
