Before this commit, when we click on social tags in the Settings,
it opens a pop-up while redirecting to the home page in the main window.
The redirection is not intended.
This is caused by href="#", which purpose is to show the pointer cursor when
hovering on the links. The issue is that href="#" redirects to the index page
on click, which is the home page.
This commit keeps the href while cancelling the redirection on click in the
main window.
