MozLab

If you're a Mozilla developer looking for a remote shell and testing tool, MozLab may be just what you need. The software package consists of two main components: MozRepl and MozUnit.

MozRepl allows you to connect to Firefox from an external editor or telnet client and program it interactively. This can be incredibly useful for debugging or troubleshooting, as you can quickly test various commands and see their effects in real-time.

MozUnit, on the other hand, is a graphical tool designed specifically for test-driven development. With MozUnit, you can easily create and run tests for your Mozilla projects, ensuring that they're working as expected and catching any issues early on in the development process.

One of the biggest requirements for using MozLab is, of course, Firefox itself. However, assuming you're already a Mozilla developer, this likely won't be an issue. Overall, MozLab can be a valuable addition to your toolkit if you're looking for ways to streamline your development workflow and improve the reliability of your code.
