I have a windows 98 computer and im wont let me chat on gmail! Can anyone help?

why you still use windows 98?i do not know much about windows 98.

The "older version" of Gmail was disabled in October 2010. So if you're on Windows 98, you might be able to chat in Gmail with Firefox 2.0: http://www.oldapps.com/firefox.php?old_firefox=7?download

<< Gmail chat is supported on the older version of Gmail in Internet Explorer 6.0 and Firefox 1.0. In the newer version of Gmail, you can use chat with Internet Explorer 7.0+, Firefox 2.0+ or Safari 3.0+, and Chrome. >>
