Chrome still doesn't have a couple of what I consider are my vital extensions, so I still use Firefox whenever I can. Problem is, with all the extensions I use on it, plus the fact that I usually have something like 20-30 tabs open across several windows, Firefox has kind of become a bloated beast, consuming an awful lot of system resources :-( No more!!!! Thanks to an episode of Tekzilla I discovered BarTab, which keeps all the background tabs unloaded, only actually connecting when you click the tab to view. Where it comes in even handier is when FF is starting up, say after a crash or update, when BarTab will do the same thing with all the tabs I had open. Instead of fully loading them all, really slowing the startup process, it only fully loads the main tab, leaving the rest grayed out until you actually need to revisit one of those tabs. I've noticed a significant increase in performance since installing it a couple of days ago - try it out!
