Whether you have one or 75 tabs, it can be frustrating when they are closed by accident. But restoring them to normal is not too hard of a process.

If you want to restore multiple tabs, or if you need a tab you closed a while ago, just keep pressing Ctrl+Shift+T and your tabs will reappear in the order in which they were closed.

Chrome is testing a new Session Restore Infobar in Canary that replaces the old crash dialog and restores tabs automatically after restart.
