how to hide link fragment

How can i avoid displaying link fragments for tabs.

I am using tabs to display contents on home page. By default contents under first tab is displayed. No fragments appear in the link. However it still has '#' at the end of the link.

When i visit to www.example.com, the url shows up as www.example.com#

This messes up with the condition applied on path for restricting display of any block.

For example if i want to display certain block only when the path is
www.example.com/show-block

I apply the path condition as show-block/*

Due to tabs on this page, the url shows up as www.example.com/show-block#

So the above condition does not work.
