Hide information on the URL bar & the Explorer tab

[wisam]

I have a question, which is asked from my client.

"When browsing on any of our storefronts, the URL bar shows the full
string of where the shopper is on the site, and the Explorer tab shows
the HTML commands pertaining to the category description.

Is there a way to disguise, hide, or shorten this information. It does
not look good and does not feel very secure..."

Can anybody provide some information on this?

Thanks.
