tomcat - How to read Firefox log

Question

I have a question about the log of Firefox Browser.

I am implement the automatic update feature of my Firefox extension, after following the tutorial at http://www.borngeek.com/firefox/automatic-firefox-extension-updates/ and getting some helps at post Firefox extension automatic update feature, the update feature is still not working, but there are more information provided at the Firefox log. Can anyone please give me some advices or take some time to take a look at the log output. Thanks.

My development environment is

1. Firefox 5 on Ubuntu 11.04
2. Tomcat 6 server

The log output of a remove and re-install my extension is

This log shows installation of an extension with ID myextension@mozilla.myextension.org from disk. Nothing special here - installation is scheduled, after a restart it is actually completed. Nothing about updates in that log (I guess that the installation was triggered manually).

Log entries referring to update checks rather than installation start with "addons.updates" and not "addons.xpi". When an update manifest is being checked you should see an entry "addons.updates: Requesting https://..." as well as additional entries in case of issues. Make sure that extensions.logging.enabled preference is set to true and that you actually trigger updates check - right-click your add-on in the add-on manager and choose "Find Updates" from the context menu.
