Black-list mode
: Apply the custom user-agent string to all tabs except the tabs with the following top-level hostnames (comma-separated list of hostnames). Note that even if a window-based user-agent string is set from the toolbar popup, your browser's default user-agent string is used.
White-list mode
: Only apply the custom user-agent string to the tabs with following top-level hostnames. Note that if a window-based user-agent string is set from the toolbar popup, this user-agent will overwrite the global one.
Custom mode
: Try to resolve the user-agent string from a JSON object; otherwise either use the default user-agent string or use the one that user is set from the popup. Use "*" as the hostname to match all domains. You can randomly select from multiple user-agent strings by providing an array instead of a string.
Insert
a sample JSON object.
Use caching to improve performance (recommended value is true). Uncheck this option only if you are using the custom mode and also you need the user-agent string to be altered from the provided list on every single request.
