This Chrome extension adds a button to right of the omnibox when a CRX file has been detected. By default, this is only enabled on the Chrome Web Store. Upon clicking the button, two actions become available:
- Download extension as zip file
- View source
The "View source" option opens a new tab with a simple viewer, with the following features:
- Download-as-zip at the upper-right corner.
- List of file names, and the option to filter files with a regular expression.
- Automatic beautification (formatting) of code
- Syntax highlighting
- Image preview
As mentioned before, this extension activates on the Chrome Web Store by default. It's also possible to view the source code of Chrome and Opera 15+ extensions that are hosted somewhere else. Further, there's an option to show a contextmenu entry on links whose target is a Chromium extension. Both features can be toggled at the options page.
The "View source for all extensions" only shows a button when it detects the download of an
extension. This detection is implemented through MIME-type sniffing using the
declarativeWebRequest
API, which is only available to Chromium beta/dev users (though it should soon be available to the
general public).
