Get Firefox set up with the pages on the tabs that you’d like to have there when it opens, then click on Tools/Internet Options/General tab. Click on “Use Current”.
Yes, I use iGoogle.
It pops up, I see my stocks, some widgets for teams I like, NY Times headlines, weather, ESPN Headlines.
I have a link to maps, gMail, etc.
I use a tabbed browser, and my iGoogle page is always my first tab. I find it odd that seasoned net surfers wouldn’t use one. Don’t you have pages/informaion that fits on a home page that you visit every day?
On the rare occasions that I actually start my browser (it’s always running, and I always standby or hibernate my PC), it just loads that tabs I had open last time [ETA: I think this is a feature of the TabMixPlus extension that I use]. Just checking now, it seems that my home page is Google UK. But I have also removed the Home button from my toolbar because I never use it.
At work, my home page is our company’s intranet page. At home, it’s my LJ friends’ page. No particular reason, it’s just one of the places I visit frequently. I’m in the process of building my own.
Yep, I do the same thing. The really nice thing is, I can access that from anywhere. If I want to show something to a friend at his house, the link is there waiting for me.
I use NPR for a home page, but I’m confused about tabs as well. I use them, but I probably don’t make good use of them.
At work, sadly, we’re still using IE 6, so no tabs yet.
At home, my Mac opens to my ISP’s site for no particular reason other than laziness on my part. It’s a very sparse, fast-loading page, so no particular worries. If I want to open with Google, I just tap a button on my drawing tablet and a Google box pops up. (Technically, it brings up Dashboard, but it’s still quick as a wink.)
From there, yes, CMD-T brings up blank tabs, which I use with reckless abandon, especially since Safari was updated to ask “You’re about to close five tabs. Continue?”
At work it just goes to our intranet site. My home home page is set to Play.net.
My “home page” is always set to CNN.com. Why? So I can keep current at least with the headlines of the day, if not the actual “news”. 
Nope. My first task at my computer each day is checking my e-mail, for which I use a dedicated e-mail client and an account connected to my own domain name. Part of checking my e-mail is my SDMB “Reply to Post” notifications, so the first things I actually look at on the Web are those SDMB threads.
That’s followed by the 31 webcomics I read regularly. I suppose I could have all of these load in tabs and call that my “home page”, but since they don’t all update on a daily basis that would be a waste of time and bandwidth, even with my broadband connection.
Then I read Cecil’s column for the day, and then I start perusing the SDMB for new threads of interest.
As for the stuff typically found on a home page/portal: I use the “weather widget” tool of the Mac OS X Dashboard for weather forecasts (I just hit F12 for this); for news it doesn’t take long to type “cnn.com”; for sports scores … baseball is the only sport I follow closely, so I get that information directly from the Seattle Mariners site and in any case I likely listened to the game the night before so I don’t need to check the score, and the Mariners site provides links to other baseball stories of interest; I don’t have a stock portfolio; I don’t read my horoscope.
ETA: Also, all of the Mac browsers have had a Google search field right there in the toolbar for some time now, so I really never even need to visit google.com (the preferred search engine can be changed in most cases, too).
CNN at home. I usually want to check the news headlines first thing in the AM. I usually use the tabs in Firefox to open additional pages.
Gmail is my home page so that I can obsessively check all of my e-mail accounts at once. Precious, precious e-mails, like tiny droplets of gold-tinted joy!
I use a blank page. Typically I have a destination in mind when I open Firefox, and so I don’t need to load a welcome screen just to bypass it. If I want to go to iGoogle, I’ll go there.
I actually use both, depending on what I’m working on. If I’m reading SDMB threads or doing research on computer issues, all the various pages that get opened get tabbed. If I need to open, say, Gmail while doing that, I’ll open a new window, since Gmail has nothing to do with the SDMB or the research.
I use tabs by default, but if I’m working on several different things I’ll open other browser instances and use tabs in those instances to help me group stuff a little better.
You’re probably aware of this, but in case you want to try to circumvent mgmt’s policy on IE (unless it’s a compatability issue or something), I believe there’s an add-on for FF that makes the window look like an IE window. Or maybe it’s Netscape.
That’s what I do at work. I made a webpage of about fifty links that I regularly use. It’s about as pretty as a shopping list, but it saves me tons of time during the day.
iGoogle, with weather and news on it. And Mr. Fox, who brings me great joy with his predictable daily routine.
Firefox, iGoogle, blank tabs. You know, like Og intended! 
You mean I should circumvent the policies that I enforce? :dubious: Actually, I could have FF or the red-haired stepchild known as Safari for Windows if I could demonstrate a business need and get approval and so on. Not really worth the effort.
If I could use FF, I would, and I wouldn’t bother making it look like IE.
My home page is hotmail, so I can check email before going to the fun parts of the internet.
