I've been using the "Show shortcut when selecting text" feature in Firefox, where clicking the AI ​​icon after selecting text gives me quick options like "Quiz me," "Explain this," etc. But I've run into a issue: after a certain FireFox update, when I select text and pick one of those options, Firefox does open the Copilot AI sidebar (which I've set as my default), but it doesn't actually do anything after that—it just shows the Copilot new task screen without sending the selected text or performing the action.
