Feature request: preserve form data from unloaded tabs

[captainsiberia]

Say I'm typing a message into a form, and the browser crashes. It's a long message that took me a half-hour or more to work out. Under normal Firefox behavior, when I re-launch the browser, all the form data will still be there, and I can finish working on my message. But if BarTab is set up not to load the tab, or to unload it for any reason, my message vanishes into the ether. There should be an option to preserve simple form data like that; in fact, this should be the default. Could you work this in?

Sidenote: going to see if Lazarus addon might be able to help me on this front.

Further comment: for those plagued by this issue, Lazarus is a viable solution.
