User Reviews
Users report that the add-on can correctly change the browser's time zone with instant updates and can be useful for services like AWS, but reliability is inconsistent. It works well for some sites and tasks, yet breaks many others and can cause date-related issues. It also interferes with certain sites (YouTube, hCaptcha) and even opens ads/tracking pages on install. DST handling is incomplete. Overall, it’s handy for testing or per-site display, but not dependable across the web. Pros
- Changes the browser's displayed time by adjusting the timezone parameter with immediate effect across sites.
- Generally works well for many users and scenarios, with multiple reviews noting it functions as intended.
- Useful for displaying a different time for specific services (e.g., AWS) or for testing time-related behavior across websites.
Cons
- Inconsistent across websites: works on some sites but breaks others, making reliability low overall.
- Breaks a significant number of websites or causes date-related issues beyond simple timezone changes (e.g., date pickers showing incorrect dates, 'Invalid Date' errors).
- Interferes with certain sites or checks (e.g., YouTube, hCaptcha) and can block or disrupt functionality.
- Opens an ad/tracking page on install and uninstall, which is undesirable for many users.
- Does not properly account for DST, leading to improper time handling in some scenarios.
Recent reviews
Extremely disappointing. The user interface is clunky, unintuitive, and poorly designed. More importantly, the extension lacks geographical neutrality by excluding an entire country and its major cities like Jerusalem or Tel Aviv. A timezone tool that manipulates global data for political bias is unreliable and unprofessional. Switching to a better, more inclusive alternative.

Is Change Timezone (Time Shift) Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Change Timezone (Time Shift) requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.
Change Timezone (Time Shift) may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
