I know what you mean. I currently have 10 windows open, each containing various tabs of stuff I've been researching and I can't wait to get them closed off. I would be fine with an accident but unfortunately I'm too smart for my own good and have setup safeguards for that, like having [SessionBuddy](https://chrome.google.com/webstore/detail/session-buddy/edac...) installed in Chrome (which keeps snapshots of all open tabs and windows with the option of saving/naming/editing windows/sessions).
