Welcome to DevMo

The new home of developer.mozilla.org is under construction at developer-test. Please come see our plans and progress, and join our rapidly-growing community!

Welcome to developer.mozilla.org! This site aims to collect and index documentation about Mozilla, a cross-platform internet suite and application development platform. Currently we host only the reference documentation for XPCOM, Mozilla's Cross Platform Component Object Module framework; the bulk of our existing documentation is still on the main site.
