How to set up multiple homepages in Firefox: Great Firefox tip from Lifehacker. Is this documented?
If there’s more than one site you always visit after starting up Firefox, you can set your homepage to open several tabs of different web sites at once automatically.
From Firefox’s Tools menu, Options, General, enter the addresses of sites separated by a pipe |, as shown above. Or, you can open up all the sites in tabs and hit the “Use Current Pages” button.
I've been using this trick since I first switched back at 0.8. I've got several web apps that I interact with throughout the day, and this is great to open them all at once.
The only drawback is that clicking the Home button will then attempt to re-open all of the sites in new tabs. So if you've got three sites set up as homepages and all three are open in the first three tabs and you are in a fourth tab on another site and you click the Home button, the 4th tab will be replaced with the 1st homepage, then a 5th and 6th tab will open for the other two homepages.
It was a little difficult to adjust to at first, but I have since learned to live without the Home button because those 3 tabs are always where I want them to be and I do all of my surfing on tabs 4 and on.
This also works for the current Mozilla (1.7.8) aka SeaMonkey.
