Problems This Solves

!

Google's mandatory Manifest V3 deprecation breaks your older V2 extension, requiring a complete code rebuild.

!

Your extension gets rejected by the Chrome Web Store reviewer due to permissions creep or confusing privacy statements.

!

Poorly written content scripts slow down the user's web page loading, driving immediate uninstalls and bad reviews.

!

Struggling to implement secure user authentication, database syncs, and Stripe payments inside popup windows.

Methodology

Our Proven Process

1

Manifest V3 Architecture

We design declarative content rules, least-privilege permissions, and non-persistent service workers.

2

Popup & Options Page UI

We build lightweight React-based interfaces for popup menus and settings views.

3

Content Script Injections

We write secure scripts that safely inject floating panels or sidebar overlays into target websites.

4

VRAM & CPU Profiling

We audit extension memory allocations to guarantee no lag on active browser tabs.

5

Web Store Review Launch

We document privacy rules, submit the package to the Chrome store, and manage approvals.
