Mozilla’s Firefox and Thunderbird are both open source, where the current source code is freely available. Anyone can modify and build the product, creating a new version of Firefox that might improve performance, add functionality, enhance performance using the compiler’s CPU-specific features, and even fix bugs.
You have two choices as to what happens to your work. The first choice is to keep it as your private work. The second choice is to make it part of the official product’s code.
