I think this is not feasible anymore for all users. It was discussed at long, users coming from other browsers, plus our historical users, rely on tab moving through all the results. We now also recently introduced tab-to-search, equivalent to other browsers features.
With bug 1608766 if the panel is closed tab moves to the next widget.
If the panel is open, we could maybe introduce an a11y pref to make tab move between one-offs and results, though it will have a cost, since it will introduce a disabled-by-default navigation mode that may not be well tested by normal QA operations, thus it may break subtly with time. Of course it will need a thorough automated test.
