Description

22 days ago
User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:58.0) Gecko/20100101 Firefox/58.0
Build ID: 20171101220120

Steps to reproduce:

When I open the laptop (Alienware 17 R4) and try to open Mozilla Nightly, it opens the process (when it requires updates, it installs them) but not the actual browser. 


Actual results:

The process is opened in Task Manager and if I try to open Nightly again, it opens another process (every time I try to open the browser it creates another task), but the browser does not appear (neither in the task bar, nor on the screen). 
Workaround: If I close the task (or in the case that I open multiple processes by trying multiple times to open the browser) and after that open Nightly, it opens as normal and no additional issues occur. 


Expected results:

It should open the browser and not only the process. 

Thank you. :)

Nightly process when the browser doesn't appear

I tried to close the browser because it was consuming ~7,5 GB of RAM with only 8 tabs opened.
When I tried to open it again, same issue as in the description occurred (the browser didn't open but the process did). 
Also I don't find it normal for so much RAM to be consumed. 
Until now I never checked how much RAM was consumed while using the browser. 
I will provide an update when I notice any additional issues.
Please troubleshoot with Safe Mode: https://support.mozilla.org/kb/troubleshoot-firefox-issues-using-safe-mode

Please find attached some basic troubleshooting made with Safe Mode.
May I ask for you to be more specific regarding what is needed? 

Additionally, how can I do some performance testing on Nightly? I don't have the necessary time to try some heavy load using Safe Mode.
