Update Chrome Extension to Manifest V3 & Fix Bugs


Is your Chrome Extension showing warnings about Manifest V2 deprecation? Google is actively disabling older extensions. If you don't migrate to Manifest V3 (MV3) soon, your extensionand your userscould be lost.


I am a specialized Browser Extension Developer. I don't just write code; I rescue existing projects. I will professionally audit your source code, fix lingering bugs, and migrate your extension to the new, compliant Manifest V3 standard.


  • Manifest V3 Migration: Converting background pages to Service Workers (the hardest part!).
  • API Updates: Replacing chrome.webRequest with declarativeNetRequest (if applicable).
  • Bug Fixing: JavaScript errors, UI glitches, and API connection failures.
  • Store Compliance: Ensuring your code meets the latest Chrome Web Store privacy policies.


Why Me?


  • Experienced in refactoring legacy code.
  • Deep understanding of the asynchronous nature of Service Workers.
  • Clean, commented code that is easy to maintain in the future.


Please contact me BEFORE ordering. V3 migrations vary in complexity depending on your background scripts. Let's discuss your project first to give you an accurate quote.
