Download extension

Fixes selected tab after close occurs, returning you to your previous tab instead of the random one next to the one you closed.Automatically selects the previously selected tab if you switch to a tab, and then close it. No longer will you be left at some random consecutive tab. Also works if you detach a tab from the current window you will return to your previous tab instead of next to the one you removed,

Especially useful when you have so many tabs that you must view them before close, and you happen to guess right about which one to close, only to get lost in a sea of unlabeled tabs, forced to find which one you were just on.... well... not anymore.... If you need to manage more than just one previous tab try my other extension LasTabZ linked below.
