However, note that the extension might not reflect the latest source in our master branch.
(The above link is updated upon every merge to our master branch).
For an experimental Chrome extension, get the code as explained below and issue `make extension`.
Then open Chrome with the flag `--enable-experimental-extension-apis`, go to `Tools > Extension`
and load the (unpackaged) extension from the directory `extensions/chrome`.
### Getting the code
To get a local copy of the current code, clone it using git:
$ git clone git://github.com/andreasgal/pdf.js.git pdfjs
$ git clone git://github.com/mozilla/pdf.js.git pdfjs
$ cd pdfjs
