Who creates these extensions?

Why aren’t extensions built-in to Firefox?
One of the main purposes of extensions is to give you the ability to customize your browser in your own unique way. Even though there are thousands of extensions to choose from, chances are you will only need, or use, a small handful of them.
One of the goals of the developers of the Firefox is to give you a minimal default browser with which to start with. This reduces the number of possible bugs in the software, and the amount of computer memory that your browser uses.
From there, it’s all up to you as to which extensions you’d like to add.
