But one thing I’ve noticed in an account that has been blessed by google is that if you connect to https://mail.google.com – the chat functionality doesn’t show up. but if you go to plain ol’ http://mail.google.com and log in- the chat does show up.
So from my experience, it looks like if you’re willing to not have SSL all the time in google mail, you can gtalk in the browser.
Kind of a bummer, or is it a bug?
NOTE: this was observed on Firefox 220.127.116.11 on Mac OS X
