We each have our special needs.
I don't use breadcrumbs which left me with an issue for the product details page. The customer may want to return to the product listing.
I want my site to be as friendly to the least computer literate as possible so I have inserted a button below the description below the product description:
====================
<div align="center">
<br>
<form>
<input type="button" value="Go back to the previous page"
onclick="history.back()">
</form>
</div>
=====================
I know there is a browser back button - try talking on the phone to a customer who is getting confused; tell him/her to click the back button. Look at your browser as a total novice - where is it? Most of my customers are at the other end of the spectrum to the smart programmer.
Adding navigation aids is crucial and need to be independent of the browser.
I doubt this answers your specific question,prakash, but I hope this is helpful to someone.
