I don't usually have more than 30 tabs open, my problem is separating them by 'topic'. To a degree I can solve that with different browsers or profiles, but when clicking a link on irc or in a mail or twitter it always opens in the default browser. My main gripe there's no way to have real context switches there, then again maybe I would just have to find a way to send a certain tab to a certain browser instance with a keyboard shortcut...
