The only homepage that Firefox is starting with is my own. I used to open Netvibes as well using the simple | separator that makes it possible to open more than one homepage during Firefox startup. But what if someone wanted to open different homepages depending on the weekday ?
Maybe you would like to open a local news website, or one that is displaying the latest stock exchange news, from Monday to Friday while you prefer a entertaining website for the weekend.
Morning Coffee is a Firefox extension that can set different homepages for each day of the week. It is theoretically possible to open several different homepages on each day. If you have a homepage that you would like to open each day you can add that as well because there is a section called Every Day.

Urls are simply added by selecting a day or the Every Day entry and clicking on the add button afterwards. Sites can be opened in random order for the extra thrill and tabs can be closed before opening the websites.

You change your mind on extension cutting? :))
Yeah, this is good thing indeed.
I use special bookmarks folders before, but this is better.
Roman I still have only ten extensions installed :)
Martin, I better pay for exra GB of RAM (DDR2 is pretty cheap nowadays), than restrict myself to 10 extensions. ;)
Well 10 is all I need ;)
