Do you "Tab" while You Write?

While writing or editing, I always keep my internet browser open. In fact, my browser will contain a slew of tabs already connected to v. important websites. I do this before even attempting to open my Word Document--a lesson I learned after repeatedly interrupting a train of thought just to hop onto the internet.

So, which tabs do I have open at the moment?

-Dictionary.com
-Thesaurus.com
-YouTube.com (I'm in the mood for a song I don't already have on my computer)
-Google (it's open to a list of information on fire burns)
-Wikipedia (It's open to an article on tarantulas)
-Google Images (looking at tarantula pictures)
