Is librewolf-crash-reporter.exe a Virus or Malware?

How to Tell if librewolf-crash-reporter.exe is Legitimate or Malware
- File Location:: Must be in C:\Program Files\LibreWolf\CrashReporter\librewolf-crash-reporter.exe or C:\Program Files (x86)\LibreWolf\CrashReporter\librewolf-crash-reporter.exe. Any other path is suspicious.
- Digital Signature:: Right-click the executable in Task Manager or File Explorer → Properties → Digital Signatures. Should show a signer like "LibreWolf Project".
