Content Security Policy (CSP)

DOM injected scripts that would be executed immediately upon injection into the page will execute as you might expect. Imagine a content script with the following code as a simple example: Note that this will execute regardless of the policy a page may specify. However, the behavior becomes more complicated both inside that DOM injected script and for any script that does not immediately execute upon injection. Imagine that our extension is running on a page that provides its own CSP that specifies script-src 'self'.

Now imagine the content script executes the following code: This is because the script did not immediately execute and code not interpreted until the click event occurs is not considered part of the content script, so the CSP of the page not of the extension restricts its behavior. And since that CSP does not specify unsafe-inline , the inline event handler is blocked. The correct way to implement the desired behavior in this case would be to add the onclick handler as a function from the content script as follows: Another similar issue arises if the content script executes the following: However, take this case: That is, while the initial script execution is allowed, the behavior within the script will be regulated by the page's CSP.

Thus, depending on how you write DOM injected scripts in your extension, changes to the page's CSP may affect the behavior of your extension. Since content scripts are not affected by the page's CSP, this a great reason to put as much behavior as possible of your extension into the content script rather than DOM injected scripts.
