What our analysis found
Spoof Timezone, used by 40,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites and can inject scripts into pages. It comes from a trusted publisher and was last updated in July 2026.
Analyst notes
The extension's behavior is entirely consistent with its stated purpose: it spoofs the browser's timezone by injecting scripts to override Date and Intl APIs. All permissions (host_permissions on all URLs, scripting, webNavigation) are necessary for this functionality. No data exfiltration, tracking, or malicious code was found. The IP geolocation calls are user-initiated or opt-in (via update-on-startup setting) and are transparent in the extension description. The ML model likely flagged the broad host permissions and scripting, but these are inherent to the extension's core feature.

About this extension
Change the time zone setting for web pages in the browser to a randomly selected or user-specified time zone.
Read the publisher’s full description
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.
