I'm currently working on an extension for Google Chrome which should extract all links from the web page the user is currently on and list them in the window that is opened upon clicking the icon. For that I need to access the complete DOM page content of the active tab from the browserAction html, which is what I can't really make up.

I already took a look at this repository https://github.com/dvidsilva/chrome-ext-sample which should basically be what I want but when I try to use it in my browser I get an error:

Refused to execute inline script because it violates the following
Content Security Policy directive: "script-src 'self'". Either the
'unsafe-inline' keyword, a hash ('sha256-...'), or a nonce
('nonce-...') is required to enable inline execution.

• Now my first attempt was to use the mentioned unsafe-inline keyword but it is blocked in browser extensions from what I can tell (is Content Security Policy 'unsafe-inline' deprecated?, Chrome Extension - Content Security Policy - executing inline code).


• Afterwards I tried using the hash from the text but it is ignored, as an insecure CSP value.


• I can't really find an example on how to use the nonce tag on the web.

Now my question is how do I access the page content from the browser action or how do I set the CSP to run my scripts?

Thanks for your help

  Are you using an inline script? Then don't. Use a separate js file as shown in the extension you've linked. More info. As for the web page, it's a separate page, not related to the browserAction popup so you need a content script, see How to access the webpage DOM rather than the extension page DOM?
