The quick answer is NO!
If you force links to open in new windows by using the target="_blank" attribute:
- The user is no longer in control of their browser’s behaviour: users should always be in control of their online experience.
- Users expect to open links in the same window: that’s the way most of the web behaves. If you open a new browser window for them, they might not notice, and then they’ll be disoriented: they might not understand why they can’t back up to the previous page by clicking on the back button or the backspace key and become frustrated.
- Users generally don’t like to deal with dozens of opened windows or tabs and will quickly become disgusted with your website.
