Notes:
- You can easily set custom "user-agent" strings from the toolbar popup

- The extension does not use any resources when it is not spoofing the user-agent
- 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.
- You can set per-site user-agent strings
- There is an option to randomize user-agent strings.
- It is possible to set user-agent string for a single window; you can have a separate user-agent string for each browser window
