Thank you! The extension hangs under the tab and shows up when you hover over the tab. This breaks on Mac OS X and Linux plus the keyboard shortcuts don't work on these platforms. I am as surprised as you are that it doesn't work cross platform. Also thank you for posting more information about Tyba - it's much appreciated.
