So I installed Nightly yesterday. It ran great. Today, I went to quit and restart with the quit button from the menu. When I tried to reopen Firefox, it kept instantly crashing without a crash reporter window showing up. And I can't reinstall it because the installer appears to have disappeared from my computer and no matter what i click, on the download pages it gives me a download for an old version of Firefox that's not even Nightly. Now I understand this is Nightly and it's a bit less stable but I was definetively not expecting this. I don't know where I went wrong with this and how this happened, but help would be appreciated.
