Text chat
Chat in Gmail isn't yet compatible with all of our supported browsers. 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. We're working to make chat compatible with additional browsers. In the meantime, we suggest downloading a chat-supported browser. Mozilla Firefox is available for free download at: http://www.mozilla.org/products
Voice and video chat
In order to use Gmail's voice and video chat feature, your computer should meet the following requirements:
- Microsoft Windows XP, Microsoft Windows Vista, or Mac OS X on an Intel-based Mac
- Firefox 2+, Safari 3+, IE6+, or Chrome
- Broadband connection to the Internet
If you're using voice and video chat over a corporate network, your network administrator should ensure that it has ports 80 and 443 open. For the best voice and video quality, we also strongly recommend allowing UDP over any port.
