This is the missing feature that is making me think I should return to my old browser.

Loss of tabs on close, and no prompt to close when multiple tabs are open.

Closed my browser on accident last night, and now I must sit here and dig through my last weeks history to try to find all of the tabs that closed with a single missed click.

I installed this browser to test it out on recommendation, and so far it's not bad, but I am a habitual multi-tabber. With no window recovery, or close protection, I find this browser lacking.
