Removing Host Permission from Extension

[Malcolm Mason Rodriguez]

I have an extension with a content script that works on "<all_urls>". I want to make this permission optional but am a bit confused on how to do that. 

Do I simply add the following to my manifest?

"optional_host_permissions": ["https://*/*"],

And do I have to remove or add anything to content.matches?

{

"matches": [

"<all_urls>"

],

"js": [

"content/index.js"

],

"run_at": "document_start"

}

For dynamic content script,

in manifest.json,

1. add "optional_host_permissions"

2. remove "content_scripts" entirely

in your code, let users enable/disable this optional function. when the user enables it

1. request host permission

2. dynamic register content script

Thanks for the response Jackie! What warning does the scripting permission display when the user attempts to add the extension?

[Jackie Han]

1. When users install your extension from the Web Store, no host permissions warning display.

2. When you request host permission by chrome.permissions.request(), users will see host permission and decide whether to grant it.

3. chrome.scripting.registerContentScripts() itself doesn't display any warning, but without host permission it doesn't work.

4. "permissions": ["scripting"] doesn't display warning when install the extension
