Browser extension to spoof your timezone, geolocation, locale and user agent.
|
|
|
|
## About
|
|
|
|
This extension allows you to customize your browser's settings to appear as if you are accessing the internet from a different location, locale, or device. This can be useful for testing websites, bypassing regional restrictions, or protecting your privacy online. With just a few clicks, you can change your time zone, locale, geolocation, and user agent to match your desired settings.
|
|
|
|
Most extensions that provide anti-fingerprinting features rely on content scripts to inject script tags into webpages. There are many limitations to script tag injections which you can read about here: https://palant.info/2020/12/10/how-anti-fingerprinting-extensions-tend-to-make-fingerprinting-easier
|
|
|
|
Vytal utilizes the chrome.debugger API to spoof this data. This allows the data to be spoofed in frames, web workers and during the initial loading of a website. It also makes the spoofing completely undetectable.
|
|
|
|
Vytal is not a VPN or proxy and will not change your IP. Although it can be used in combination with a VPN to obscure your true location.

## Limitations
|
|
|
|
### Debugging bar
|
|
|
|
While the chrome.debugger API is active, a bar under the address bar is displayed. Hiding the bar is only possible when the --silent-debugger-extension-api command-line switch is used.

|
|
|
|
### FireFox
|
|
|
|
Unfortunately Vytal doesn't work on Firefox since Firefox doesn't support the debugger API for extensions. https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/permissions#browser_compatibility
|
|
|
|
### New tab
|
|
|
|
The chrome debugger cannot attach itself to chrome://newtab. This can result in data leakage to the first non chrome:// page you navigate to.
|
|
|
|
### Locale override does not mock language data
|
|
|
|
Unlike the Chrome devtools location sensor, overriding the locale does not change language data (such as navigator.language or navigator.languages). There is an open ticket about this here: https://bugs.chromium.org/p/chromium/issues/detail?id=1306254
