In this case you could download the extension or theme on another computer and transfer it using a flash drive.

注意：如果由于某种原因手动安装扩展程序或主题仍然失败，则可能是您的防病毒软件或其他下载监视软件可能损坏了该文件。 在这种情况下，您可以将扩展名或主题下载到另一台计算机上，然后使用闪存驱动器进行传输。

Method 4 – Restart Firefox After “Failed Add-on Installation”

方法4 –“附加组件安装失败”后重新启动Firefox

• If you are installing directly from the Mozilla Add-ons website, there could be a problem with the Mozilla Add-ons website database or with a broken mirror website. Restart Firefox to see if the extension or theme did install regardless of the“Invalid file hash (possible download corruption)” error message. 如果直接从Mozilla附加组件网站进行安装，则Mozilla附加组件网站数据库或镜像网站损坏可能存在问题。 重新启动Firefox，以查看扩展名或主题是否已安装，而不考虑“无效的文件哈希(可能的下载损坏)”错误消息。

Method 5 – Other Alternatives

方法5 –其他选择

1. Try installing the extension or theme again at a later time 稍后再尝试安装扩展程序或主题
2. Try installing the extension or theme from the add-on creator’s personal website 尝试从附加创作者的个人网站安装扩展程序或主题

Hopefully with these tips you can bypass the error and enjoy more Firefox Add-on goodness.

希望借助这些技巧，您可以绕过错误并享受Firefox附加组件的更多好处。
