Firefox hangs with white window on Windows 10

After installing Firefox on Windows 10 it never opened, the process just kept running but no window ever opened. Then I copied all of the files from my backed up profile to the new profile and now Firefox opens a window but it is completely white and it hangs forever.

Running Firefox in safe mode does the same thing.

I'm attaching a screenshot with the white window

Never mind it seems I found the issue. Nahimic for MSI was running and it seems that causes Firefox to hang

Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see

Configure firewalls so that Firefox can access the Internet. {web link}

Deactivating the firewall did not solve the issue. It did however open the Crash Reporter. This is the error that appeared
