Aurora is an “alpha” build of Firefox, which means it’s undergone minimum testing only. As such it’s not suitable for everyday use, which is why Firefox Aurora is installed as a separate build alongside the stable or beta build, allowing you to test its features without affecting your day-to-day browsing. Settings are shared between Firefox Aurora and your other build, however, so again caution should be exercised before installing it.

According to the Mozilla blog, Aurora will be synchronised with the Nightly Build server every 5-6 weeks, which means it’s significantly less stable at the start of this period than at the end when its changes migrate into the Beta channel.
