Notes from group review: - Skip empty string for env var when building `yarn webpack metamask-extension/development/build/set-environment-variables.js:203 throw new Error( ^ Error: Invalid phishing warning page URL: '/' `

The implementation looks good to me. Approved ~

LGTM ! Thanks for the changes, gonna be such a life-changing

@NiranjanaBinoy the feature looks solid, If you can append a short demo of the deletion feature, it would help a lot to refine and manual testing as well 🙏🏻

LGTM !
