I didn't look for such and just hold the Control or Shift-Control depending on the effect I wanted.
I use Slimbrowser because I like the tab setup where each web page open a new tab.
I just downloaded Firefox and see it has tabs but maybe I've missed something looking at the help file. Can I set it up like Slimbrowser so each website I visit opens a new tab instead of replacing the old website in the current tab and without selecting "New Tab" from the File Menu.
Thanks in advance,
