Image right-click/context menu has been broken for months.

Ever since the UI update months ago, right-clicking an embedded image does nothing, where it used to bring up Firefox's normal context menu, including options for opening the link in a new tab/window (since it's both a hyperlink and an image). Clearly you are cancelling the context menu event, but you are not providing any alternative functionality to replace the lost feature. Heck, even if you were, the browser's built-in context menu has a ton of useful actions, and keyboard shortcuts on all of them to boot.

Unless there's some mod-only menu that I just don't have access to, but in that case turning it into an utter no-op is still dumb for usability, because it trains people to never right-click images, so if they got access to a menu later, they wouldn't think to even try.

This broken browser feature is especially noticeable when you want to save a copy of an image. You used to be able to right click, press k on your keyboard, and immediately have a "save as" popup for the original. Even if the browser was lagging momentarily (video-game-induced low-memory situation, browser needing half a second to page something back in oughtn't be that rare an experience), the inputs would queue and resolve as muscle memory would expect them to.

(There are workarounds, but they're all terrible in other ways. Firefox lets you toggle "dom.event.contextmenu.enabled" off, but then the working discord-provided right-click menus break. Firefox also lets you shift-right-click to force the built-in menu to appear, at the cost of substantial extra finger strain, the mental overhead of overriding muscle memory, and the extra second to coordinate both hands for the click. And it would leave mouse-only users (holding a mug of coffee while scrolling through the night's memes? Too bad) without the option to set their favourite as a desktop background, save it to pocket, send it to a different device, or any of the other non-basic context menu entries that are surely part of someone's workflow, as if "open in new tab" wasn't good enough for them.)
