All added links open as target, how to prevent it? In my Drupal based website, all links that I added from CKeditor open as (target="_blank"

Link example: (&lt;a href="node/add/name"&gt;Name&lt;/a&gt;)
After adding, example from html source: (&lt;a target="_blank" rel="nofollow" href="node/add/name"&gt;Name&lt;/a&gt;)


As you see, the 'target="_blank" rel="nofollow"' added automatically.

How can I solve this problem?
In CKeditor  when adding a link it will ask 

click -> hyperlink button ->in Target set it as  will resolve your issue. 

or if you have installed external  module means disable it.
