Installing the latest builds of Firefox allows us to catch bugs earlier in the development process. Without all of the awesome help we get from community members we would never be able release a product at the quality level that we do. Installing a nightly build gets more eyes on more parts of the web. By using some of our tools, we are able to see what our top crashers are and act on the bugs before we hit the main stream. People who notice that something is wrong and file a bug are able to help find bugs that we would not have otherwise found.
Does my have a nightly build?
Yes! All of our major platforms including mobile have nightly builds.
How do I get the Builds?
