我想象你的代码是提高WindowsError: [Error 2] The system cannot find the file specified: 'C:\\Program Files\\Mozilla Firefox (x86)\x0cirefox'。特别是，注意到这个错误是应该是\f的\x0c。

你需要躲避反斜杠在你的文件的路径，否则你会在不知不觉中引用转义序列\f。

os.startfile("C:\\Program Files (x86)\\Mozilla Firefox\\firefox")

或者，您可以使用raw string。

os.startfile(r"C:\Program Files (x86)\Mozilla Firefox\firefox")

或者在文件名中使用正斜杠，即使在Windows上也是如此，并避免反斜杠问题。 –
