Try to download Firefox from this page: http://www.mozilla.com/firefox/all.html

Thanks for reply. Had tried that without success, then decided to try Netscape site, which offered a few alternatives, one of which was "Flock". I was able to download and install it and happy to say am back in business, able to print, and do other things that had stopped working for me with Internet Explorer. Will see how it goes from here, and report back in due course.
