Firefox, AppArmor - self-update - Tutorial
Several weeks ago, I wrote an article that provided a basic overview of the AppArmor hardening tool, explained how it works, and showed you a practical example on how to confine and harden the Firefox browser. But wait, not just any which Firefox, but specifically the tarball version that you can download from Mozilla. I'm talking about the tar archive. Grab, extract, run.
So far so good. Using the AppArmor profile (template) from my Kubuntu installation, I was able, with small modifications, to create a custom ruleset for the Firefox tar version running from my home directory. Things are fine, but there be one problem. By default, it cannot update. We shall fix that now.
