how to set firefox up so that ea URL you type in or click on from bookmarks will open in a new tab

Personally I do not like the new firefox. My bookmarks will not open in a new tab automatically when needed, it over rides the current tab that is opened. Additionally I am constantly being bothered with a unrelated pop up every time I open a new tab. and the Firefox logo used to appear so that you could click on it and get to firefox's home page. New version is horrible. may have to abandon and use another browser.
