I am always having this problem of losing all of my open tabs. I am sure I am not the only person who has many parallel task running. Then, for whatever reason, the browser crashes, and in opening the browser, the single "Restore Previous Session" button is the only lifeline back to all of that work. Would it be too much to ask for a simple session restore feature that is indexed to history? So we could go back to yesterday's session, or last week's, and not lose so much. This loss of ongoing work happens to me 2-3 times a year, and amounts to untold losses of time, effort, and money.
