I'm developing a migration update from XUL to Jetpack. I want to simulate the process on my local machine, make sure that everything works as expected when the versions change.
I followed all the steps of this tutorial: http://www.borngeek.com/firefox/automatic-firefox-extension-updates/ in order to make a self hosted update version. But the extension won't update and I'm not getting any errors.
How can I debug, or at least initiate the update process for an add-on?
First of all, you should toggle on the extensions.logging.enabled preference. This will dump a lot of information about the update process and states into the Browser Console.
After enabling the preference, just open the Add-ons Manager UI and search for updates again.
But to test that stuff still works from going from one version to another, I would just install the old version (in a new profile) and then drop the new version XPI. This will trigger the same code paths as would have been triggered if the update XPI was retrieved over the network.
