A new version of Gmail is available. The only thing different I can see is a robust address book.
It also warns users if they have Firebug enabled. Yikes!
Have you seen any other improvements or changes?
Check your Gmail account now and you’ll know if your in the new version if in the upper right corner, after settings, there is a link that say “Old Version.” Clicking it will take you back to the old version and a “New Version” link will appear.
I’m still hunting for new more features.
