How can I prevent Safari from removing first words of tabs' titles?
According to this macworld article I don't believe that there is a fix yet (if you really want this fixed, you could try searching for terminal commands to fix or disable this feature). Otherwise you could try switching browsers...


  When you use tabs, Safari sets the tab's title to include the domain name as well as the page title. For instance, macosxhints.com - Submit a Hint. However, when you have more than one or two tabs opened on the same site, Safari drops the domain name from all the tabs, and just includes the page title: Submit a Hint
