Tracking symbol not showing in the tool bar

Apologies as I am no techy, but have activated the trial tracking protection but no symbol is present in the tool bar as shown in the graphics explaining how it works. I have no confidence that its actually working. Any advice is welcome.

I have the same problem. I enabled TP but no icon. I opened add-ons and it is listed. I Disabled and then Enabled but still no icon.

The icon will only show in the location bar if/when 3rd-party trackers are blocked. See also
