My main browser is Firefox, but I like Chrome’s short startup time and general javascript speed. Here is a useful tip if you use Chrome. Chrome doesn’t ask for confirmation if you close a window with multiple tabs. Don’t worry, it is very easy to bring those back. To bring the last session press CTRL+SHIFT+T simultaneously and your last window will popup.
This is also true across sessions, i.e. if you completely close Chrome or after you restart. In these cases open a new Chrome window, then press this combination and you will get another window with your last set of tabs.
