I don't know. You could try reading the firmware Release Notes documents, but they tend to be nearly information-free.

Perhaps. Or an error or oversight. With the usual documentation, it's tough to do more than guess.

You might explore the HTML, and see if something on that page has been commented out in an easy-to-restore way. I do little of that, so I know nothing, but I believe that Firefox has a whole bunch of stuff under Tools > Web Developer.
Have you tried one of the Telnet Enable tools floating around out there? I use the program which I modified: http://antinode.info/nte/
The feature has apparently been gone from the R7000 for a while. I don't recall seeing any reports of improvement or work-around on that model.
