I downloaded the version "a2pre" version of FF 3.7 for Linux. Posting from it now. It looks the same as 3.6 on my box. I'm sure it will change some before final release, but suspect that there will be an option for a "Classic" interface.
That calls for a party on my side
Since as much as I like firefox, I would probably switch to opera if they went "chrome".
Well hopefully no matter what they'll still let us configure it. I'd hope they not take that away or the option for more themes and control of the bars.
I very much hope so, since the freedom to configure firefox in pretty much any way is the main reason why I like it so much. I remember when I upgraded to 3.5 they took the close button off the last tab. Took me quite a bit of googling and messing with about:config to put it back on.
