I use Firefox and Chrome mainly . When there is a link provided in the comment/answer/question , the link redirects to a page from the existing tab rather than opening a new tab & displaying it there.
for eg: Left Click here . By default , the site appears in this same tab and not in a new tab.
The same problem exists when it comes to the mobile site.
I'm not saying that there's anything wrong with it but why can't the links be opened in a new tab automatically rather than having to do it manually?
