Hi.
I don't think the idea is new, but here's a problem I ran into.
1) Closed the browser to refresh. After closing it, it did not refresh, nor did it start (control panel and taskbar).
2) There were about three dozen tasks from Mozilla in the Dispatcher. I understand these were open tabs from the last session, and if I closed them all, I would have lost them.
3) Eventually, the browser started from the icon on the desktop. And, far from the first time, it was as if it had been frozen for a few minutes.
The idea is to have the browser, if the user closes it, independently terminate the processes displayed in the dispatcher. Without losing the history of open tabs (as in chrome).
If I closed Mozilla processes in the manager (I usually closed them myself before), I lost all open history (I rarely have less than fifty tabs open at once).
