The only thing preventing me from leaving FF to move to Chrome is TabMixPlus (especially multi-layered tabs), considering I regularly have 20-30+ tabs open simultaneously. Scrolling through tabs on Chrome is a very painful experience, and as such, my Chrome experience is limited to occasional moments when FF feels too clunky and needs to be restarted.

If there is a Chrome extension that allows this, please let me know, because I've been unable to find one.
