What happened to the "When switching to a tab" option ?When starting the browser, and the tabs opened when we last closed FF are restored, BarTab stops them from loading them when not active, but now the tab DOESN'T load anymore when we switch to a not-loaded-yet tab, I remember this option worked some time ago, but not anymore .... Perhaps that's the reason the option has disappeared from the options screen ?Too bad, better addons will show up.

EDIT : Indeed, as already stated here previously, the whole "BarTab" functionality is now by default in FF4.
