Both of you should use this Add-On to simplfy "Tabs" - ColorfulTabs. It's one of the few I use and makes each tab a different color, so they stand out better.
I detest "tabs" in the browser. For me it is a clumbsy and cumbersome interface.
Tigger, the last time I installed the Sun Java crap, it broke several other applications (including IE, which prevented me from getting Windows updates) I had installed at the time. Sun may know Solaris, but I will never trust a Windows product from them again. Yes, they insist on dialing home and popping up a Window, when you least expect it, to tell you about an update. Yes, another unneccessary background process.
You can shut that crap off, but they still manage to dial home when you are browsing around.
