This has been a problem for at least a week. Reproducible: Always Actual Results: File not found Expected Results: Download and/or install of XPI file.
I click "add to firefox" and get https://addons.mozilla.org/en-US/firefox/downloads/file/72179/isadmin-2.2-fx+tb+sm-win.xpi which works fine. This was probably a transient issue.
