Creating a new browser window should be the authority of the user only. Do not try to pop-up new windows to clutter the user’s screen.
All links should open in the same window by default. An exception, however, may be made for pages containing a links list. It is convenient in such cases to open links in another window, so that the user can come back to the links page easily.
Even in such cases, it is advisable to give the user a prior note that links would open in a new window.
Pop Up Window Tips:
- Tell visitors they are about to invoke a pop up window (using the link <title> attribute)
- Popup windows do not work in all browsers.
- They are disorienting for users
- Provide the user with an alternative.
