I had Firefox 4.01 installed on my PC, and I recently updated it to get the Aurora which I noticed allows you to change between Aurora, the Beta, and the Release, which I loved, but I also downloaded Nightly too. Nightly works great and I was able to run both programs no problem, however, I noticed with the new update for Nightly, whenever I run Aurora, it opens up Nightly. I install the release of 4.01 again and it still opens up as nightly, what should I do?

Make sure that you close all other browsers before opening Aurora. Otherwise Firefox will find the already running Nightly build and open a new window in that process. Also make sure that each version has its own profile folder.
