Unload unused tab groups from Memory onto Hard drive
An OPTION that allows users to unload tabs/groups out of ram memory onto the hard drive when they haven't been viewed for a specified amount of time, is i think really important.
This would allow Firefox to be extremely fast all the time, especially if it is programmed in such a way that those tabs and groups that are on the hard drive cache get ZERO CPU time and are invisible until the user views them again, in which case they get pulled back into ram.
This would allow dozens, hundreds of tabs to run smoothly. I have quite a lot of tabs running all the time, and even on my i5 core high spec pc, Firefox can become slightly jerky in it's response if i go overboard, say 200+ tabs - i know that's a lot, but people multitask and from one site you end up opening so many tabs.
Ideally background tabs/groups should get zero CPU time and only the focussed tab should get it, but i imagine that's really difficult when websites use so many scripts, flash, etc.

I originally thought this was a dumb idea. But these days, Firefox is consistently using up 1.9 gigs of RAM (on a system with 3 gigs and no swap,) so if I have FFX open I cannot use *anything* else. I know that using more than 100 tabs is specifically not recommended by the dev team, but that just doesn't fit the reality of how people use web browsers these days. If you can't gracefully have 300+ tabs open, your browser isn't worth using. Therefore I'm changing my mind-- this is a good idea.
Just installed BarTab,and what a difference it does make:Firefox is now so much faster when dealing with many tab groups-developers should IMHO find a way of integrating this feature by default,tweaking it to work with Apptabs & Tabcandy.
I agree this is essential - since having Tab Candy I tend to have lots of tabs just left open in the background. However I've had a couple of occasions where Firefox is attempting to use 100% CPU due to a rogue tab, and it's been difficult to identify which tab is causing the problem (if tabs/groups could be automatically or manually unloaded it would make it much easier to narrow down the search)..

Sounds like a logical idea,moreover ,maybe Firefox shouldn't load all tabs from a previous session at once,since this leads to an extremely slow (I would dare say unacceptable,if this wasn't a beta) start up especially with several tab groups.
A button to MANUALY do this would be nice :-)
I think this is essential too. Tab Candy invites the use of many tabs which can remain open for long periods of time and open tabs eat up lots of memory...
I also think this is essential. Tab Candy invites the use of many tabs which can remain open for longer periods of time. My iMac quad core i7 nearly grinds to a halt sometimes when I've got 120+ tabs open. I'm a journalist working on several stories at a time and tend to be a tab whore as a necessary part of my work. Perhaps this concept can be linked with the #1 requested feature which is saving groups. They are, in a way, very much related. Some of the UI integration ideas expressed in other other comment for this feature are also excellent!
That would be an essential feature to me. FF crashes regularly when I have lots of tabs open.
It would be nice, if upon being saved, the thumbnails of the saved tabs can be viewed (and searched) in a directory-like manner (with sublevels and such). Also, it would be even better if a user could click on any such thumbnail and resurrect the tab and also asked if the user wants to resurrect the whole group.
I found addon called GroupBar :o also possible to group and unload tabs pretty crazy
Domicius, thanks for the headsup on that extension, installed it and loving it so far.
There's already an extension that does this: BarTab. Hopefully it will be ready to work with TabCandy in time for public release.
