Say I define different contexts or workspaces. So in my address bar I can type work and it will open up 5 pages that will be associated to that keyword. Then I can type bored and it will open up my 4 defined pages associated to that keyword.

I am NOT asking about pinning pages to the start/home page, and I am NOT asking about loading websites when Firefox starts up (because I don't want to always load the same things every time I launch ffox). I am also not asking about pinning tabs.
