Sometimes when I'm researching on a software issue (i.e. a bug that I most likely created), I google a lot and so have a lot of tabs open in FireFox. I don't use IE :)
But FireFox only allows me to save the open-tabs for the last session. Is there a way that I can sort of command FireFox to obey => for this FireFox main window containing all these open tabs, save the session as name "researching on bug #232 -- file is not saving" so that I can come back later and click on a button to have all those tabs open up again.
