How do I get the URL of the active tab in Firefox/IE/Chrome?

[He Jibo]

Hi,
I am writing a small program, which needs to get the URL of the active
tab in either of firefox, internet exploerer or chrome.
My need is similar as the one posted at, http://stackoverflow.com/questions/3631
... -ie-chrome

I did a lot of Googling, and get the following code. The following
code can get the url of the first tab in internet explorer. My
question is, how can I get the url of the current active tab? Thanks.
