Mozilla announced it will start giving away Jetpacks to users, but you can't use them to fly around your neighborhood or to stir up general mayhem. So what exactly can you do with it?

"Specifically, Jetpack will be an exploration n using web technologies to enhance the browser (e.g. HTML, CSS, and JavaScript), with the goal of allowing anyone who can build a website to participate in making the web a better place to work, communicate, and play," Mozilla wrote in a blog.

Oh. Well that's cool too, we suppose. Apparently, Jetpack will be the tool for building the next generation of add-ons, and according to Mozilla, they can be written "in under a dozen lines of code." But it's not just developers who should be excited.

"More importantly, from a user-perspective, Jetpack will allow new features to be added to the browser without a restart co compatibility issues, resulting in little to no disruption to the online experience," Mozilla added.

Color us officially excited again.
