How can I test CSP in my browser extensions?

You can test Content Security Policy (CSP) in your browser extensions by using the browser's developer tools. Start by loading your extension and then open the developer tools. Look for the 'Console' tab to check for any CSP violations.

What specific tools or methods should I use to check for violations?

You can use the built-in console in Chrome or Firefox to see CSP violation messages. Additionally, tools like CSP Evaluator can help analyze your policy.

Are there any common mistakes to avoid when setting up CSP for extensions?

Yes, common mistakes include overly restrictive policies that block legitimate resources, or not including necessary directives like 'script-src' or 'style-src'.

Can I test CSP in a local development environment?

Absolutely! You can load your extension in developer mode in your browser and test CSP locally. Just ensure your local server is configured to serve the extension correctly.
