Another issue I found with the context menu is how often extensions add unnecessary actions that you can do nothing about except opening the browser toolbox and hiding them the ugly way. I don't think it's reasonable to expect every extension to add their own, unique settings for disabling context menu actions. I'd much rather we have e.g. a universal, Firefox provided UI to edit and disable context menu entries.
The latest culprit is, funnily enough, Firefox Relay, which adds a "Manage all masks" action... I'm never going to click that. It opens your relay account page. That's it. We have several other ways to do that. I don't need the option to manage all masks when I'm copying an image, or translating text, or opening a link in another window, etc. There are probably users that want it, but I'm not them; it's just clutter.
Earlier this year the right click option on tab menus added this annoying 'load tab to right' option above the 'reload tab' button. I don't want this nuisance!
