Of course:

#appMenu-addons-button[shortcut]::after {
   display: none;
}

PS. Try to learn how to use the code Inspector, instead of asking about every simple thing.

From my experience the inspector would only allow you to analyse webpage assets. When I hover the cursor over a part of the UI there does not seem to my any change in the console. Clearly I'm doing something wrong I suppose...

Either way, I'm done now.

Thank you for the answer.

You need to use the Browser Toolbox and not the Inspector for the user interface. You can enable this toolbox via the developer tools settings page (F1).

Fantastic. Thank you.

Now how do I keep the browser toolbox focused/not minimized to the taskbar when opening menus to inspect elements not immediately available on a given page?

Tip: ui.popup.disable_autohide = true.

^The Browser Toolbox has this as a choice in the three dot (...) menu (Disable Popup Auto-Hide). If you change the pref directly on about:config then all menus stay open unless you toggle the pref to default (false).
