User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:52.9) Gecko/20100101 Goanna/3.4 Firefox/52.9 PaleMoon/27.9.0a1 Build ID: 20180326150806 Steps to reproduce: I am normally browsing the web using Firefox. I stop and close Firefox window. I now want to browse the web again and click on the Firefox icon to launch the browser. Actual results: Nothing happens (no UI or error message appears). When I view the task manager (Process Explorer from Sysinternals) I see a firefox.exe process running consuming 100% of one of my CPU cores). When I close this process using task manager and try to restart Firefox the same thing happens: firefox.exe process launches, consumes 100% of one CPU core, no UI/error message. When I kill the firefox.exe process and go to %localappdata%\Mozilla\Firefox\Profiles\<myProfile> and delete contents of "startupCache" folder, Firefox will be able to start again like expected. Expected results: Firefox should start normally or shown an error.
This is happening on a notebook with SSD storage running latest Windows 10 Home edition/build. I first saw this happening ~January. It is happening every now and then.
