Select a table on a website. In the context-menu, everything is greyed out.
Even when I manage (by accident) to get the context menu not greyed out, "copy" (no matter what) does not copy anything to the clipboard.

Totally useless

Many times select column is greyed out! (only next/prev table is clickable)

Selects rows and columns as expected, but copies only the whole table and only as text (default Firefox behavior). Unfortunately, useless.
