You'll have to point your links to a Rails action, passing the external URL as a parameter.

So instead of:

 = link_to "http://rubyonrails.org/"
 # => <a href="http://rubyonrails.org/">

You would link to:

 = link_to open_url_path, url: "http://rubyonrails.org/"
 # => <a href="/open_url?url=http%3A%2F%2Frubyonrails.org%2F">

Then you can pass the url from your controller to the view:

def open_url
  @url = params[:url]
end

And render the HTML containing your toolbar and iframe:

<div id="toolbar" />
<iframe src="<%= @url %>" />
