What this service covers

A browser extension can streamline repetitive work, enhance approved websites, connect internal tools, or add a focused interface to Chrome. I define the supported pages, user roles, data flow, required permissions, and privacy implications before development.

The implementation can include a popup, options page, content scripts, service worker, storage, authentication, messaging, downloads, and one or more approved APIs. Permissions are kept as narrow as practical. Sensitive tokens are not embedded in client code when a server-side exchange is required.

Store listing preparation is available, but the client owns the publisher account, fees, privacy policy, and legal disclosures. Chrome Web Store approval and review timing are controlled by Google. Support for other Chromium browsers or Firefox is tested only when listed in scope.

Frequently asked questions

How long does Chrome extension development take?

Delivery takes 3–20 days based on workflows, permissions, interfaces, supported pages, APIs, and review cycles. Store review time is not part of development delivery.

Can you publish it to the Chrome Web Store?

I can prepare the package, listing assets, and technical submission details. The client owns the publisher account and policies, while Google controls approval and timing.

Will it work in Edge, Brave, or Firefox?

Many Chromium APIs are shared, but compatibility depends on browser version, permissions, and APIs used. Each supported browser is listed and tested; Firefox may require separate work.
