Are the "groups" persistent and tied to the window? So if you change the tabs around, close the window, then "open" the group again, you will get exactly what you had?
They are persistent, but I don't think they are tied to a window (I mainly just use one). But your groups are kept as you left them after restarting.
I have 7 groups right now on my home machine, and that many or more on my work machine. Each has a few to a large number of tabs in it. I have about 28 in my current one. Each group contains tabs about a different topic, such as daily visit sites, searches and articles for ongoing development in a particular language, research into specific projects, or random lookups.
I also use the Tree View Tabs extension which show tabs in a hierarchical list on the left, instead of across the top. This is a better use of space for me and shows the relationships of tabs.
I am going to miss both of these severely if the XUL plugins go away this fall as they are saying. My web workflow is much more efficient with them, at least in Firefox. I like using Chrome, but with a lot of pages open I just have a squished up mass of tabs across the top that can't be easily read, it's a big bother.
Anyway, I wish there were more extensions for more browsers that improved the state of managing large groups of tabs by topic.
Last time I tried the groups that were opened when quitting firefox would reopen at next launch but you could not "reopen" a closed group. Having more than one window was asking for trouble as in risking losing all your groups and tabs because there another firefox window opened in the background or the downthemall manager window when you closed the main firefox windows.
Workaround is to always quit firefox using the ctrl+q shortcut, though at times groups will reopen with the correct number of tabs but they're all empty.
Best bet is to manually save your session at times.
