The extensions page could only hand out tarballs; installing meant going to Settings › Extensions › Community and finding the entry again. Pages now get window.bcnr.installExtension(id) and Theseus intercepts theseus://extensions/install/<id> links (page clicks, target=_blank and the address bar). The page only names a catalog id: Theseus fetches the catalog and package itself, asks in a native dialog the page cannot draw over, verifies the publisher signature against the name's current owner and activates the add-on — the same path a Settings install takes. One prompt at a time; an already-installed version says so instead of offering a no-op update. The site shows the button inside Theseus (feature-detected on the bridge), a "update Theseus" hint on older builds and a download hint in other browsers.
