How do I update the Content Security Policy in my existing browser extensions?

To update the Content Security Policy (CSP) in your existing browser extensions, you'll need to modify the manifest file. You can add or update the 'content_security_policy' field to specify the new policy.

What should I include in the new CSP?

Your new CSP should include directives that specify which resources can be loaded. For example, you might want to allow scripts from specific domains or restrict inline scripts.

Can you give me an example of a CSP for a Chrome extension?

Sure! A basic example for a Chrome extension could be: "default-src 'self'; script-src 'self' https://example.com;" This allows scripts from your extension and from example.com.

Are there any common mistakes to avoid when updating CSP?

Yes, common mistakes include overly permissive policies that can expose your extension to security risks, and forgetting to test the new CSP to ensure it doesn't break functionality.
