Safari can create a New Tab by clicking in the blank space next to a tab which you don't have until after you use the Command+T option to create a new tab.
Also, the New Tabs that are created do not open with your HomePage but just a blank page until you install my button.
These are the main features and use of this button. Those that are giving it a bad review are not thinking about all of that before posting their bad reviews. This is a feature that has been in Firefox for a long time and I'm bringing it more...
RequirementsMac OS X 10.5 or later, Safari 3.1.X.
