Spoof websites trying to gather information about your web navigation to deliver distinct content you may not want

Usage example: You can alter your user-agent string to indicate you?re on a mobile device if you prefer seeing mobile versions of sites so they load quicker.


This extension allows you to spoof your browser "user-agent" string to a custom designation, making it impossible for websites to know specific details about your browsing arrangement.

Video overview:

1. You can easily set custom "user-agent" strings from the toolbar popup
2. The extension uses a two-factor technique to mimic your default "user-agent" string, which is the most reliable method
3. The extension does not use any resources when it is not spoofing the user-agent
4. The extension enables user-agent spoofing on specific domains only; it is conversely possible to exclude certain domains from spoofing. Check the Options page for more info.
5. You can set per-site user-agent strings
6. There is an option to randomize user-agent strings.
7. It is possible to set user-agent string for a single window; you can have a separate user-agent string for each browser window

The best and most advanced UA spoofer extension, perfect for developers and troubleshooting stupid UA sniffer issues.

I used it to change user agent on my Android phone using the Kiwi browser. It worked perfectly. I changed the android version to 3 in order for the Facebook website to be displayed correctly.
