HELP! Google Chrome went unresponsive when I went to a wrong page, and when I restarted, it DID NOT RESTORE ALL MY TABS! How do I find the tabs to restore?

Unfortunately, the browsing history page only records the pages I have opened, not the pages I have closed, and the Closed Tabs list only records the pages I closed deliberately, not by freezing crashes. (At least not this freezing crash.)

I hate to sift through days worth of history to find which sites I left open because I opened them at different times.

Moreover, what Chrome add-on can I download that will save ALL tabs I have currently open, that works similar to the FireFox add-on.

(No, I don’t wish to go back to Firefox. It has caused more problems than Chrome does.)
