This morning when I started up Firefox it had a pop-up about the new profiles feature, asking to create a new profile. Just out of curiosity I clicked the create profile button to see what the interface would look like. Since I didn't actually want to create the profile I hit the delete button, but nothing happened. So I closed the window. I then tried delete the new profile (then called "Profile 1") by hitting the trash can from the choose profiles screen. Still nothing happens. At this point my original profile window is still open, but I close everything to restart Firefox in hopes that it will allow me to delete this profile I never wanted to begin with. The Choose profile window comes up, I select original profile and nothing happens. I can open the new "Profile 1", which I have since labelled "Bad Profile". D:\Users\<USERNAME>\AppData\Roaming\Mozilla\Firefox\Profiles doesn't appear to have my original profile anywhere. I'm deeply concerned this beta feature I never asked for has deleted my original profile when it should have deleted the new profile.
