Hey there! System: Windows 10 x64, Firefox Nightly. '''Problem:''' Out of the blue, when I start Firefox Nightly (I think 2-3 days ago), it just crashed with no extra info. I see the "window of the update process", it goes to the middle or to the end, immediately closes and doesn't bring up the Crash reporter. '''However!''' When I tried to run a Nightly Installer that I downloaded through Chrome, it quietly runs and then just opens up my browser no problem, profile and all. I checked and it seems to be the exact same .exe file (according to the Task Manager). So in short: it breaks if I run it straight from my usual shortcut, or with .exe. But if I run the installer myself, the browser opens up fine. However, the installer didn't bring any new updates that would fix the problem, I have this for 2-3 days now, I don't remember. I start working, I see I didn't fix it and run the installer again. Any ideas on the fix? I would love to not lose my profile, settings and, if possible, tabs. I'll try disabling all the extensions after I post this, I don't think they contribute, though (seeing how the external Firefox Nightly Installer opens up my browser just fine). Thanks in advance!
