Many years ago, I found an obscure setting that enabled a toolbar that would display all those document links directly in the browser. That was several computers ago, so I cannot look up the about:config setting that enabled the functionality, and my online searches have found nothing even remotely related to the subject.
What happened to that functionality? How can I turn it back on inside the latest version of Firefox?
Addendum: This functionality was not provided by any extension, add-on, or mod. It was implemented directly in the browser itself, downloaded vanilla and clean installed. It was enabled by directly editing the "about:config" page.
As for whether the cited links are intended for automated tools or not, here is the HTML standard itself:
Interactive user agents may provide users with a means to follow the hyperlinks created using the link element, somewhere within their user interface.
And just in case somebody suggests this is somehow new or novel functionality, here it is described in the HTML standard published in 1997:
Although LINK has no content, it conveys relationship information that may be rendered by user agents in a variety of ways (e.g., a tool-bar with a drop-down menu of links).
That "tool-bar with a drop-down menu of links" is almost exactly what Mozilla used to provide. I just want to know what happened to it.
