You'll also note that in Firefox, when you open 40-50 tabs(of different content from different sites) at once... it still functions very well indeed. (IE7 chokes on that many, yes, I have it Loaded on a Windows machine here)
But, those annoying tabs being super small can be taken care of with an extension for the tabbar. It lets you set the minimum width for a tab, then stacks the tabs once you reach the maximum tabs per line. The extension I am using is called Flowing Tabs, the one Drew Uses (and as do I) is called Tabbrowser Preferences.
You aren't really getting it, are YOU?
If you want to see functionality extended, you should really try FireFox and the Extensions written for it. I believe there is something like 400 now? Just checked, 559 Extensions. Ability to be eXtreme at personalizing your FireFox. Hey, lookey that most all of them thar Extensions work on any platform FireFox is written for.
Now, let us not get started on themes. 103 as of right now. Yeah. some are lame, others are Freakin Awesome, most are good.
