author

Type String
Mandatory No

Example
json
"author": "Walt Whitman"

The extension's author. It's intended for display in the browser's user interface. The string held by value is a localizable property.

Firefox expects this key to represent the name of the person or entity that developed the extension. If the developer key is also specified as an object with a name property, the value of name overrides the author key.

Using the developer key to identify the author in Firefox is recommended.

As of May 2025, Chrome and the Chrome Web Store don't use this key.

Example

json
"author": "Walt Whitman"
