Is Allow CORS safe?

Clean risk

Allow CORS rewrites CORS response headers for all pages to match the active tab origin when enabled.

When the extension is turned on, it reads the active tab's origin and installs a browser network rule that changes CORS response headers for XMLHttpRequest, main-frame, and sub-frame requests. The rule sets Access-Control-Allow-Origin to the active tab origin, sets allowed methods from the user's popup choices, and sets Access-Control-Allow-Headers to '*'.
