Mozilla has unveiled Jetpack, a project to make Firefox add-ons easier to code and deploy.
Most importantly, from a user perspective, Jetpack will allow new features to be added to the browser without a restart or compatibility issues, resulting in little to no disruption to the online experience.
What's notable is that Mozilla is clearly stating that its lineup of browser add-ons is a competitive edge. Add-ons could become the equivalent of applications for an operating system. But today add-ons can be a hassle. If Mozilla can make add-ons simple and lightweight Firefox may have an edge on Google's Chrome, which downplays add-ons over speed concerns, and Microsoft's Internet Explorer.
