Quite good extension, but unlike Ctrl+Tab extension it does not let you switch to the immediately former tab you've focused (as the OSs windows managers usually do), instead it only switches among tabs in incremental sequence, which is a big drawback to me.
The visual inteface is neat, but seems a bit slow to me drawing tabs thumbnails.
