I'm not sure whether this is a problem with Firefox's menu/settings, or with how the page is designed. '''''Built-in Features''''' One option is using the built-in context menu feature, right-click or Ctrl+click, then "Open Image in New Tab" to send the currently displayed image to a new tab. Another option is using the built-in context menu feature, right-click or Ctrl+click, then "Open Link in New Tab" to send the link behind the image to a new tab. '''''Page Design''''' It sounds like you are clicking in an image gallery or image search results page. Pages can direct a link to a new tab using either ''target="_blank"'' in the link HTML, or by attaching the ''window.open()'' script command. These are usually invisible to you as the user. It's possible that the behavior of the links in the page has changed, but it's hard for me to know unless it's a site I also use. If you want to force a link to a new tab, these are the usual methods: * right-click > Open Link in New Tab * Command+click (on Windows, Ctrl+click) * if your mouse has a middle button or scroll wheel, middle-click the link For search sites, they often have a setting to choose whether to open in a new tab or same tab, in case that might be relevant.
