The Open in New Window Plugin Plugin uses JavaScript to target external links to a new browser window, leaving your blog page open.
Since it uses javascript, it targets more links than using a plugin that filter pages and rewrite the link. The plugin will find many links generated in scripts or pasted into posts and comments.
Due to the limitations of javascript it will not be able target links in iframes such as Adsense and some other affiliate links.
This plugin is free and I expect nothing in return. If you wish to support my programming, buy my books:
