How do I use this?

I googled to find out how to make a link to the previous page and found this.
Is this the thing?
The information about this module is not very descriptive so I do not know if this module can solve my issue and, if it can, I do not understand how I shall implement this.
What I want to do is the following:
In a view header, I have placed this:
<p><a class="backbutton" href="/en/menu-front"><span class="text"><<</span></a></span>&nbsp;&nbsp;<span class="taskcaption">How many?</span></p>
What I want is to replace this absolute link: href="/en/menu-front" with a dynamic link to the previous page.
Is this possible with this module enabled?
If so, how do I do this?
