The Add-on "Tree Style Tab" seems to have a broken link on the Mozilla website. The button on the add-on page that says "Add-to Firefox" points to an add-on called "Hide My Ass IP Checker". Attempts to install the Tree Style tab add-on install the "Hide My Ass IP Checker" instead. Here is the link I am using to get to the Tree Style Tab page: https://addons.mozilla.org/en-US/firefox/addon/tree-style-tab/ And here is the link provided by the "Add to Firefox" button: https://addons.mozilla.org/firefox/downloads/file/215288/hide_my_ass_ip_checker-1.5.1-fx.xpi?src=dp-btn-primary I was trying to re-install the Tree Style Tab add-on and ran into a a problem. Can you please fix the link? Thanks. Rob
