Thanks for the pointers! Ha, I sould have been more expressive. I am not interested in performance: I have written an eslint plugin to identify and disallow future patches that contain assignments of innerHTML which do not use our XSS sanitizer (https://developer.mozilla.org/en-US/Firefox_OS/Security/Security_Automation). Now I want to look at existing issues and identify those that should be fixed first. I hope that an instrumentation (and stack traces) can give me a better idea of what different code paths lead to these sinks. (On the side, I was also hoping to learn something new :)) _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
