If you look at the very end of the address area, after the star, you should see a reload button. Actually, it changes depending on the page status: after loading, it's reload, during loading it's stop, and if you start typing into the address box, it turns into go.

If you prefer separate buttons, you can use the Toolbar customization feature to move the combined button away from the end of the address box and/or split the reload and stop (change the sequence to prevent them from recombining).

View menu > Toolbars > Customize

If you have the orange Firefox button, tap the Alt key or press F10 to display the classic menu bar.

In some cases, it is easier to press Ctrl+r or the F5 key than to find the little button.

Thank you so much Jscher2000. I looked everywhere BUT there so I really appreciate your help.
