As we all now latest firefox 78 update brought some changes to tab context menu:

Changes probably were unwanted for many, including me. I would love to have an option (because firefox is always advertised as “users having choice and customisation options”) to remove sub-menu and just have these options available directly.
Such small change is somewhat annoying in long run. I use this option often and now I have more clicking to do. I know that you plan to add “close tabs to the left” soon but I do not plan to use it, and worst case scenario I can get used to having 3 options instead of 2, but it is hard for me to get used to having to hover over sub-menu, wait for it to pop-up, and finally then choose preferred option.
