Peter Ellzey
About this gig
Keep your Chrome extension working smoothly with reliable fixes and a clean upgrade path to current browser requirements.
I troubleshoot Chrome extension bugs, resolve errors, and update legacy code to Manifest V3. Whether a feature stopped working or an update broke your extension, I focus on the cause and a practical fix.
I work with SaaS founders, startup teams, online businesses, agencies, and developers maintaining existing browser tools.
What I can design:
- JavaScript bug fixes and console error resolution
- Manifest V2 to V3 migration
- Background service worker and permission fixes
- Popup, content script, and API troubleshooting
Your project can include:
- Code review and issue diagnosis
- Updated extension source files
- Tested bug fixes and compatibility updates
- Brief change summary
- Setup and testing instructions
Share your source code, the errors you see, your current extension version, and the behavior you expect. I'll review the scope, explain the approach, and deliver the agreed fixes with clear handover notes.
Message me with your issue before ordering, so we can choose the right package.

What do you need to get started on my Chrome extension?
I'll need your extension source code (preferably as a ZIP file), a description of the issue, any error messages or screenshots, and details about the expected functionality. This helps me assess the problem before starting.
Can you fix Chrome extensions that stopped working after a browser update?

Will you provide the updated source code and help with Chrome Web Store publishing?
Yes! You'll receive the updated source code, completed fixes, and basic testing instructions. I can also help prepare your extension for Chrome Web Store submission if publishing assistance is included in our agreed scope. Store approval is handled by Google.
