Firefox is running but the browser window doesn't show
Issue on Windows 10.
Was browsing normally and Firefox went sluggish so I decided to hard reboot my computer. Now Firefox doesn't want to show up on the screen. I opened the task manager and it shows that Firefox is running. Everytime I click to open Firefox, a new background process is added and not a single browser window shows up on the screen. I reinstalled Firefox and it doesn't fix the issue. I have no issue with any other program.

I had the same problem, re-create a profile and copying all data from old to new one helped me with this issue.
