Google - pages from Ireland search

The option to search for pages from Ireland on www.Google.ie is available on my PC in work. I think I'm using IE5 or 6

However, I don't seem to have the option on my PC at home - using either IE8 or Firefox.

Anyone know why this is?

Thanks.

I raised this question here a few months back.
Has google search radio button "Country Specific Filter" "pages from Ireland" gone?
