FAQ
What information do you need from me to get started?
I need a clear outline of what the extension should do, any API keys or documentation if we are integrating third-party services, and any specific design preferences or UI mockups you might have.
Will you publish the extension to the Chrome Web Store for me?
Yes, store submission is included in the Premium package! If you choose the Basic or Standard package, we can add publishing as a custom extra (Note: You must have your own registered Google/Mozilla Developer accounts).
Will I receive the source code?
Absolutely. The complete, uncompiled source code is included by default in the Standard and Premium packages. If you order the Basic package, you can add the source code as a Gig Extra during checkout.
Can you upgrade my extension from Manifest V2 or V1 to Manifest V3?
Yes, absolutely. I can seamlessly migrate your background scripts to service workers and update your API calls to comply with the latest Manifest V3 security and performance standards.
Do you support advanced features like web scraping, automation, or API integration?
Yes! Whether you need custom web scraping, robust DOM automation, or an extension that connects to scalable enterprise architectures and backends like Java and Spring Boot, I can build a solution that seamlessly communicates with your infrastructure.
Can you build an extension that retrieves cookies or uses stored sessions?
Yes, I can develop extensions that securely interact with browser cookies and active session data, provided it complies with standard browser security policies and permissions. This is highly useful for auto-login features, maintaining user state across tabs, or securely passing session tokens.
