我在更新我写的Firefox扩展时遇到问题。它似乎下载新版本，卸载旧版本，然后重新安装旧版本。
我使用以下命令打包扩展名：
cfx xpi --update-link=https://www.myextension.com/firefox/myextension.xpi --update-url=https://www.myextension.com/firefox/myextension.update.rdf
我使用about：config属性“extensions.logging.enabled”设置为true运行Firefox并获得以下日志：
*** LOG addons.updates: Requesting https://www.myextension.com/firefox/myextension.update.rdf
*** LOG addons.updates: Found an update entry for myextension@myextension.com version 0.1.1
*** LOG addons.xpi: Download started for https://www.myextension.com/firefox/myextension.xpi to file C:\Users\BENMCC~1\AppData\Local\Temp\tmp-mki.xpi
*** LOG addons.xpi: Download of https://www.myextension.com/firefox/myextension.xpi completed.

*** LOG addons.xpi: Install of https://www.myextension.com/firefox/myextension.xpi completed.
*** LOG addons.xpi: Calling bootstrap method startup on myextension@myextension.com version 0.1
它将xpi下载到C：\ Users \ BENMCC~1 \ AppData \ Local \ Temp \ tmp-mki.xpi，但随后出现从C：\ Users \ Ben McCann \ AppData \ Roaming \ Mozilla安装旧版本\火狐\ Profiles文件\ pr7jcnq3.default \分机\ myextension@myextension.com.xpi。我检查了后者的xpi，它的版本号错了。
可能会发生什么想法或如何调试问题？

事实证明这是因为服务器没有正确设置扩展文件的mime类型。
