URL for the extension's home page.

If a [developer](/en-US/docs/Mozilla/Add-ons/WebExtensions/manifest.json/developer) key containing the "url" property and "homepage_url" are defined, Firefox uses "developer.url" while Opera uses "homepage_url".
Chrome and Safari do not support the "developer" key.

This is a [localizable property](/en-US/docs/Mozilla/Add-ons/WebExtensions/Internationalization#internationalizing_manifest.json).

## Example

```json
"homepage_url": "https://github.com/mdn/webextensions-examples/tree/master/beastify"
