I loves me some FireFox tabed browsing. I frequently use tabs as ad-hoc bookmarks while holding control + clicking to open a new page for later review. To that end, here are the tabs I have open religiously, usually in this order:

1. Gmail. The epicenter of my web efforts. Work. Play. Personal. Planning. Notes. Scheduling. You name it, I’m doing it here. It’s funny ’cause I encourage everyone to email me first because it has a higher priority for me than other communication methods such as phone or voicemail, and it documents everything to boot! It’s funny, ’cause while other people use “just email me” as a brush off, I’m genuinely sincere from a productivity and response perspective. Asynchronous communication for the win! (Side note: I don’t and haven’t used Microsoft Office for over a year now minus a handful of rare, quick occasions. I use Gmail for all that now.)
2. Bloglines. Information overload and feed reading goes here. I live in this thing too, probably too much and periodically close the tab for productivity’s sake.
3. Thesaurus. This goes hand-in-hand with its dictionary counterpart and is a must have for aspiring writers like “mua” and lovers of the English language. It’s like a writers inventory: the only thing he sells is words.
4. Blogger, Blogsmith (non-public). The two most widely used blog publishing platforms that I use daily. Griffio customizes WordPress installations, however, as a nifty publishing/CMS software for our clients as well. So I’m in those a lot too. Mmm… Blogging and self-publishing for the win!
5. Wikipedia. This bad boy has stolen about 50% of my research traffic that formally went to Google. It’s quicker, faster, leverages the masses for balanced/non-bias information without all the ads. Even better relevancy than Google now. I could live on this site all day long if I had to.
6. Google SERPS. Yup, I still use the mother of all search despite my critiques of it. I use the engine for info discovery and Google images to accompany my blogging.

You will then see the rest of the tabs filled with upwards of 10-15 web pages I intend to check out later in the short-term. If I don’t get around to them, they get bookmarked and tagged in my Delicious account. Other notable tabs I consistently have open include websites I’m working on, Site Meter for traffic tracking, Delicious, Digg, and Flickr to name a few. I’m an internet junkie and would royally be out of a job if I were at this stage in my career 15 years ago when the web was non-existent. What tabs do you rock on a consistent basis?
