I'm currently downloading FF13 only because of that feature. I always have 100+ tabs open, and oftentimes, when a browser is "full" (i.e., too many tabs) I switch to another browser until I have time to clean up the mess. There were situations where Chrome, Safari, and Opera were "full". Really looking forward to this new feature.
