Open Thread: How are you using tabs?

I live in browser tabs. Whether I’m in Safari or Firefox, I’m constantly sending links to a new tab (CMD-click in either app). It’s something that most geeks take for granted but–I can tell you, I’ve seen the browser stats–there’s still a lot of folks out there living in one Window. (*observes solemn moment of silence*)

But, by far, my biggest gains come from the numerous tabbed bookmark sets that I keep in my favorites bar. These include:

• del.icio.us (home page, my page, my inbox, new and hot, daily mashup, live marks)
• MetaFilter (the blue, the grey, the green, my peeps)
• Fun break (LiveJournal Friends, Flickr contacts’ pix, Flickr ego surfing, El-Dubs board, Wrens board)

I’ve also got tab sets for finances, 43f stats, news sites, friends’ blogs, and even a set of about 10 pages that comprise the theme templates I use most in WordPress (makes for super fast editing sessions).

So. My question to you is: How are you using tabs and tab sets? Anybody doing sexy fu with Saft? Safari Stand? Tabbrowser Preferences?
