Extensions

This extension system is not ready yet!

The Chromium extension system is in active development. It is not yet ready for use by the general public. These pages contain early  design docs and reference material for the features that have been implemented, but you should expect to find lots of brokenness.

Don't worry, you're not going to miss the announcement when extensions are ready to use.
