Firefox extension update downloads but fails to install

I'm having trouble updating a Firefox extension I wrote. It appears to download the new version, uninstall the old version, and then reinstall the old version.

I packaged the extension with the following command:

cfx xpi --update-link=https://www.myextension.com/firefox/myextension.xpi --update-url=https://www.myextension.com/firefox/myextension.update.rdf

I ran Firefox with the about:config property "extensions.logging.enabled" set to true and got the following logs:

*** LOG addons.updates: Requesting https://www.myextension.com/firefox/myextension.update.rdf
*** LOG addons.updates: Found an update entry for [email protected] 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.repository: Requesting https://services.addons.mozilla.org/en-US/firefox/api/1.5/search/guid:myextension%40myextension.com?src=firefox&appOS=WINNT&appVersion=17.0.1
*** LOG addons.xpi: Starting install of https://www.myextension.com/firefox/myextension.xpi
*** LOG addons.xpi: Addon [email protected] will be installed as a packed xpi
*** LOG addons.xpi: Calling bootstrap method shutdown on [email protected] version 0.1
*** LOG addons.xpi: Calling bootstrap method uninstall on [email protected] version 0.1
*** LOG addons.xpi: Loading bootstrap scope from C:\Users\Ben McCann\AppData\Roaming\Mozilla\Firefox\Profiles\pr7jcnq3.default\extensions\[email protected]
*** LOG addons.xpi: Calling bootstrap method install on [email protected] version 0.1
*** LOG addons.xpi: Install of https://www.myextension.com/firefox/myextension.xpi completed.
*** LOG addons.xpi: Calling bootstrap method startup on [email protected] version 0.1

It downloads the xpi to C:\Users\BENMCC~1\AppData\Local\Temp\tmp-mki.xpi but then appears to install the old version from C:\Users\Ben McCann\AppData\Roaming\Mozilla\Firefox\Profiles\pr7jcnq3.default\extensions\[email protected]. I've inspected the latter xpi and it has the wrong version number.

Any ideas what might be going on or how to debug the problem?

It turns out this was because the server was not setting the mime type of the extension files correctly.

I submitted a pull request to the Play Framework to fix it.
