The problem with tabs is that they are always just a click away. It’s simply too easy to open a new tab, regardless of how many you already have open. I mean, why not open a new tab? You probably think you are being extra productive with all these tabs, but before you know it, you are drowning in tabs. You find it hard to identify one tab from another because you have so many open that you can no longer read the tab titles and are just left with a whole row of favicons. That’s not much use to anyone, but help is at hand.
