Under: about:config browser.taskbar.lists.recent.enabled false I have just made a Windows 10 system and I am not understanding the features now existing that weren't with Firefox on my Win7. I have turned the 'Frequent' off and now right clicking the Firefox icon produces 10 'Recent' listings. Being that I've changed FF's config to false, I do not know how to make these 10 'recent's permanently disappear. Right clicking one of these entities and removing only replaces with another. Please help me to permanently remove 'Recent' from my right click of the Firefox icon in my taskbar.
