Overview

Product summary

Review the store description, core capabilities, and common use cases.

The extension alters the timezone information that the browser reveals to web pages to protect your actual timezone from being identified. You can ensure the extension spoofs the correct timezone by setting your preferred one on the options page. Additionally, there is an option to generate random timezones, which can be useful in preventing fingerprinting scripts from identifying your browser based on your actual time zone.

To test the current timezone use the right-click context menu item.

The extension can also automatically detect your timezone based on your IP address starting from version 0.1.4. Use the right-click action button's menu to access this option.

Moreover, there is an option to check and update the timezone on start-up, which can be enabled from the options page.

The latest version of the extension includes improvements such as faster injection into iframes and automatic timezone detection that now respects daylight shifting. This extension now works on manifest v3.

Nice to be able to see all of the info about the timezone, but for spoofing it's unnecessary: just use the "Sensors" panel in DevTools.

It might be working, but you really need to focus more on how to make the whole user interface more user friendly. Most users can't even figure out how to set a different time zone when they first install the extension.

Was playing a game and suddenly the browser window comes up with a giant "REVIEW" button in the middle of my screen. So here you go, a review. Maybe consider not interrupting people to review your add-on when there's plenty of others that do the same thing.

Worked great for pretending to be in a different timezone for software testing.

The extension is affecting Clouflare Turnstile even when whitelisted. It causes me to fail CAPTCHA.

Работает инвалидно, верификаторы то видят, то не видят время из расширения. Но самый главный минус это то, что при включенном расширении нельзя пройти проверку на человека от cloudflare - постоянный цикл.
