Project details

Hello and welcome to my project!

Need a custom Chrome or Firefox extension built or help fixing or upgrading an existing one? I can help.

I build high-quality browser extensions for automation, SaaS products, business workflows, and custom tools. I also help fix extensions that stopped working, need Manifest V3 migration, or were rejected by the Chrome Web Store.

I can help with:
 • Custom Chrome and Firefox extension development
 • Automation and business workflow extensions
 • API, OAuth, Firebase, and third-party integrations
 • Extension bug fixing and debugging
 • Manifest V2 to Manifest V3 migration
 • Store rejection fixes and compliance updates

I focus on clean architecture, performance, and secure extension development, and I provide regular progress updates during development.

Feel free to contact me to discuss your project whether you are building a new extension or need help fixing or upgrading an existing one.

Regards,
Ozair
