It is way too easy to accidentally close all tabs. And if you don't hit the undo button quick enough there is no way to bring them all back. I didn't bookmark all of them and had been storing them over the course of a few months so they aren't just my recent history. Please allow us to go back and undo this. I want to scream explicitives at you. If I can't resolve this I will stop using this browser. I'm devastated. I feel so out of control. I hate you.
