Mozilla

About & Authors

Welcome to Mozilla Hacks!

Mozilla Hacks is one of Mozilla’s most important channels for developer outreach and engagement. We want it to be one of the key resources for people developing for the Open Web, talking about both news and in-depth descriptions of technologies and features. We will cover both development tips and tricks in general, but also look at features in Mozilla’s products from a technical perspective – to show our approach and line of thinking, and hopefully inspire other companies to implement what we have.

Mozilla Hacks is, just like MDN (Mozilla Developer Network), a web browser agnostic resource, focused on the Open Web and sharing knowledge with all web developers out there.

We feature a lot of great authors, listed below!

More in-depth information can be found in the wiki page for Mozilla Hacks.
