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

I really like this addon. I used it to change the displayed time on AWS. Is it possible to only change the time zone for a few websites?

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.

Very useful, but the only negative is that it breaks some functionality of my bank's website, so I have to disable the addon whenever I need to enter in a date search criteria on my bank's website.
A blacklist function (sites not to run the extension on) would be VERY helpful.

Does not work, I tested using this website and my timezone is still not changing https://z0ccc.github.io/LocateJS/

It works very well. But you have to disable the entire module if you want to temporarily disable/enable it.
