Many of us still miss MR Tech La Luna set up the options + (always show toolbar button).Right-click on empty space on toolbar, click 'customize' and drag it where you want it. (round icon with arrow in center)------------------------Left-click on the icon manual check for updates, right-click opens Add-ons Manager.Depending on frequency of checking chosen, when there are updates available the icon will turn blue - slide the mouse pointer up to it and it will show the available updates.
Thank you. I looked in the choices under customize last night, either it wasn't there then, or I missed it. It's there now!
