This nice page will tell you much better than I could do what's new, what's neat, what's hidden and what's broken in Mozilla 1.7b. I really love the "Show passwords" thing. Some passwords are stored there since ages (like my NYT passwd) and I forgot what it was. On a side note, there is one thing I really dislike: the linux builds are still made without Xft. It's ugly. Show the result to a journalist and the first comment will be "berk.... ugly fonts". Linux builds should enable Xft by default. As a consequence, I have thrown the 12megs download to the trash and I am building it by myself with Xft enabled. What a waste of time.
