v 52.8.0 (32 bit) - How do I move to the next email message when I have an email open and I just want to stay on the message pane I am on (i.e., do not close the message pane to return to the Inbox), and simply move to the next (read or unread) message? I do not see any option to go BACK (to the PREVIOUS) or FORWARD (to the NEXT) email? Are these buttons available for use within the message pane, and I am just not seeing them? Otherwise, it seems I have to close the message pane, which returns me to the Inbox pane (or whatever "box" I was in), and then I have to click to open the NEXT email. On the Inbox pane, however, there are options to customize and add buttons to the Menu Bar for Back, Forward, Next, etc. (or use key combinations: Go > Next....), but this is irrelevant (and fails to work) when I want to stay on the open message pane and move to the Next or Prior (Un)Open message. It seems there may have been a solution to prior versions... https://support.mozilla.org/en-US/questions/1162922#answer-974997 Thanks in advance!
