Folder Extension Wizard is a Firefox extension that adds unpacked xpi files to your addons folder one at a time. By creating a file, it loads the extensions from the selected folder. This small extension requires only the Firefox browser.

Extension Tracker is a tool that monitors your addons on addons.mozilla.org from your status bar. You can enter an extension developer's ID number and click on the tool to refresh it. It requires Firefox 2.0 or later.
