Change The Tab Settings in Firefox
Firefox has a modular design and a powerful web browser engine. It supports HTML5, CSS3, and other web standards. It also has a wide range of features, such as tabbed browsing, media support, spell-checking, integrated search, live bookmarks, and more.
By default, when clicking on a link, image, or media, Firefox will open it in a new tab but won’t switch to it. This can be changed.
