I needed to find out how to delete username entries on login pages. My search-engine inquiry took me to: https://support.mozilla.org/en-US/questions/962690#answer-447779 At that link, I find these instructions: 1 click the (empty) input field on the web page to open the drop-down list 2 highlight an entry in the drop-down list 3 press the Delete key (on Mac: Shift+Delete) to remove it I followed those instructions *to the letter,* and was unable to remove anything. Here's why: There are two different senses of the word "highlight". If I use the mouse to roll over those username entries, the entry under the arrow "highlights". Yes, the highlighting is gray - but it distinguishes that entry from the others - another sense of the word "highlight". When I press Shift + Delete in this case, the entries disappear, but remain unmodified. Note that these instructions say nothing about using the down arrow key - which is required to "highlight" [in the technical sense] the entry so that it can actually be removed with the final key-presses. The advice on this linked page should be changed to add the use of the down arrow key to the process. Please help us out by changing these instructions at this top-hit url!
