w3m can tab browsing.
I don't know this feature at all. This would be quite useful when used with screen. In most of cases, I login and do something through ssh tunnel. One thing I didn't felt comfortable was web browsing on text terminal. This w3m tab feature would help me to some extent on that problem.
