User-Agent Switcher and Manager

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.

Notes:

  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
