I apologize if this is the wrong place to ask this, but I've recently been dealing with something weird with regard to the update feature in Nightly. Yesterday, I decided to check for an update on Nightly, and it started downloading. Once finished, I was prompted to restart to let the update take affect. After waiting for a minute, I noticed nothing opening up again. I opened up Task Manager (I'm on Windows 10 Pro) and saw that both Nightly and the Nightly update service were both in the Backgrounds Processes section. After a bit of waiting, the update process vanished, but Nightly remained no matter how much time passed. I had to end up killing/ending the process/task. I did this twice more and it wasn't until the third attempt when I realized I was already running the latest version of nightly. Yet, Nightly, for whatever reason still attempted to receive/install an update. I'm sure there are already similar questions like this, but I may not have come across them. It is worth mentioning that I have both Firefox 54.0 Release (32-bit) AND Nightly 56.0a1 release installed on my system. I'm currently running two profiles: the default is stuck with just Firefox release, and I created a separate profile for nightly. Annoyingly, Nightly installs and initially runs with the default profile in use. I find this extremely annoying and prone to give errors. That aside, I followed a guide on the Stack Exchange that addressed how to get Ngihtly to run with a predefined profile. I edited the shortcut properties (in start menu folder/directory) and added to the Target field a "-p profile_name". This was done after initial installation and it's been working since then. All of the sudden, it stopped working. Not sure why. Clicking on Nightly now only opens the standard/stab;e Firefox application. What I'm most upset about is that I actually uninstalled Nightly after noticing the weird update inconsistency, and later reinstalled it. The issue persisted and I'm about to try again. Why did Nightly think it needed to be updated in the first place? I can only imagine that some kind of corruption occurred and now it's getting worse. Another last testament: I tried refreshing the profile for nightly, and it didn't do anything. When I uninstalled Nightly the first time, a folder was created in my Desktop which related to an old profile. Sine I was given no instructions as to what to with that, and noticed no performance conflict when running Nightly after reinstalling, I deleted the folder. What bug am I suffering from?
