Questions about permissions and host_permissions in new manifest v3

[Leo C.]

I have some questions about permissions in new manifest v3.

1. Do specifying host permissions in "permissions" instead of "host_permissions" raises an error causing install failure?

{
...
    "permissions": [
         "tabs",
         "cookies",
         "<all_urls>",
      ],
"host_permissions": [
                       ]
...
}

2. Do specifying host permissions in "permissions" get ignored?

{
...
    "permissions": [
         "tabs",
         "cookies",
         "https://example.com/*",
      ],
"host_permissions": [
         "https://hostexample.com/*"
    ]
...
}

Hi Leo,

This will raise a warning at install time: "Permission '<all_urls>' is unknown or URL pattern is malformed."

While this should mean the permission is ignored and the extension continues to function, you should definitely avoid putting URLs in the permissions array.
