Content Security Policy – Preview Builds October 1st, 2009

I posted this over at the Mozilla Security Blog but wanted to share it here as well. I am excited to report that Content Security Policy is available for testing! We’ve been working hard on implementing the CSP spec and now the new features are ready to be put to the test.

I would like to encourage any interested parties, whether web security researchers or website administrators, to head over to Mozilla Try Server and grab a preview build of Firefox with CSP enabled:

Windows: 1256079015-win32.zip
Mac OS X: 1256079015-macosx.dmg
Linux: 1256079015-linux.tar.bz2

Once you have it, you can test the core functionality of CSP at the demo page I set up on my Mozilla web space. There is a lot more information about this project there and I look forward to any feedback you have to share with me.
