CRX Source Viewer 제작자: Tech Interval LLC

CRX Source Viewer lets you look inside any browser extension — Chrome, Firefox, or Edge — in one click. Open the extension's page, click "View Source," and every file inside the package is right there, formatted and searchable.

What makes it different

Most viewers just unzip the archive and leave you staring at minified code. This one automatically beautifies minified JavaScript, CSS, and HTML on open, so you can actually read what an extension does.

The Analysis tab reads the manifest and explains, in plain English, what each permission actually lets the extension do — with risk levels for permissions like "debugger", "cookies", and host access like <all_urls>. If you're deciding whether to trust an extension, that's usually the answer you're looking for.

Privacy

This add-on fetches only the extension packages you ask it to inspect. It collects no analytics and tracks nothing.
