First you need to open Software\Mozilla\Mozilla Firefox and query the CurrentVersion value for the current active version.

Then, open Software\Mozilla\Mozilla Firefox\\Main and query its Install Directory value.

RegQueryValueEx is used like so;

TCHAR buffer[1024] = {0};
DWORD bufferSize = sizeof(buffer);
DWORD result = RegQueryValueEx( hkeyMain,
                         TEXT("Install Directory"),
                         NULL,
                         NULL,
                         (LPBYTE)buffer,
                         &bufferSize);
if (result == ERROR_SUCCESS)
{
    // buffer now contains the install directory
}
