I'm not sure why this is different between Windows and Mac. On Mac, this should follow a system setting called "Full Keyboard Access." If that isn't working, you can override it by changing this preference. I think. (1) In a new tab, type or paste '''about:config''' in the address bar and press Enter/Return. Click the button accepting the risk. (2) In the search box in the page, type or paste '''accessibility.tabfocus''' and pause while the list is filtered (3) Double-click the preference to display an editing field, and change the value to the preferred number (see below) then press Enter or click the blue check mark button to save the change. Possible values and resulting behavior: <table> <tr><td>Value</td><td>Text Fields</td><td>Other Fields</td><td>Links</td><td>Note</td></tr> <tr><td>1</td><td>'''Yes'''</td><td>No</td><td>No</td><td>text fields only - MacOS default</td></tr> <tr><td>2</td><td>No</td><td>'''Yes'''</td><td>No</td><td>-</td></tr> <tr><td>3</td><td>'''Yes'''</td><td>'''Yes'''</td><td>No</td><td>all form controls</td></tr> <tr><td>4</td><td>No</td><td>No</td><td>'''Yes'''</td><td>links only</td></tr> <tr><td>5</td><td>'''Yes'''</td><td>No</td><td>'''Yes'''</td><td>-</td></tr> <tr><td>6</td><td>No</td><td>'''Yes'''</td><td>'''Yes'''</td><td>-</td></tr> <tr><td>7</td><td>'''Yes'''</td><td>'''Yes'''</td><td>'''Yes'''</td><td>everything - Windows/Linux default</td></tr> </table>
