you can use HTML :
use
<head>
<base target="_blank">
</head>
in your HTML <head> tag for making all of page links which not include target attribute to be opened in a new blank window by default. Otherwise you can set target attribute for each link like this:
<a href="/yourlink.html" target="_new">test-link</a>
and it will override
<head>
<base target="_blank">
</head>
tag if it was defined previously.
