Overall good, it changes the System Time Zone parameter. The downside is that YouTube doesn't work when it is enabled.

tested works fine

Broke date picker

Il fonctionne très bien. En espérant que ça continue, encore un module délaissé semble t'il. Merci quand même au développeur, il n'y en a que deux de ce genre et celui-ci est le meilleur, merci.

Does not account for DST, opens an ad+tracking page on install and uninstall.

Как по мне отлично работает, просто надо включить, другое расширение Timezone spuff так же работает меняет время но не проходит проверки на фейковый часовой пояс, с этим всё в порядке

It still work and good.

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?

Works on some websites but not on others. Like the browser version of skype has no problem detecting the system time on my machine (even with a vpn on)

Works like a charm! A little confusing to use at first, you have to go into the extension's options to choose the timezone you'd like. What's cool is that it immediately updates the browser and instantly shows.

Not working!

Thank you very much for the add-on. Now on to the issues:

1) With certain Firefox themes, when add-on is disabled it's pretty much invisible on the panel. Please fix. A sample theme https://addons.mozilla.org/en-US/firefox/addon/linen-light/

2) Please if possible implement a list of exceptions. To ease the pain please consider subdomains from the get go, i.e. when I whitelist abc.com, domain.abc.com gets whitelisted automatically

3) https://browser.geekbench.com/v5/cpu breaks with your add-on enabled and shows "Invalid Date". Please fix.

4) Breaks far too many websites for comfort. Looks like instead of changing the web browser TZ, it actually modifies certain JS code and it does so incorrectly in many cases. I have to uninstall it. Too much hassle.

Долго не тестировал. Получилось выставить, чтобы системное время совпадало со временем ip адреса. Найти бы еще расширение, которое передвало другие данные по языку )

use this feature you will not be able to pass hcaptcha.com

Does not work anymore. Selecting any timezone has no effect, even after a restart.
