Hacks
The following projects are hacks, tools and explorations the Mozilla Labs staff as well as the wider community built – often as side projects or to scratch a particular need. We don’t treat them as proper Labs projects – you might find them useful, interesting or just fun to play with.
All projects are released under open licenses (please see the specific license for each project for details) so feel free to hack away. Please note: These aren’t supported by Labs directly, if you find a problem please contact the author or use the project’s support system (issue tracker, etc).
