During a startup update, Nightly crashes. But if I run an installer, it opens fine.

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!

A correction. My Firefox Nightly crashes ONLY when it tries to update itself specifically.

So.

Option 1) I start Firefox, it doesn't need an update - no crash. Option 2) When Firefox does have an update internally, I start a Firefox Installer instead, it opens up my browser - no crash. Option 3) When Firefox does have an update internally, I start firefox.exe, it tries to update - crash.

Are you saying that I should look for the answer there, or ask there, or something else? Cause I lurked around there and found nothing. The problem persists. I had to disable updates to continue working.
