Woohoo for Firefox tab hot keys

I'm excited to have learned the hot keys to navigate between open tabs in firefox.

On the mac...
ctrl+tab - toggles sequentially through open tabs
ctrl+shift+tab - toggle backwards through open tabs
cmd(apple key)+1 or 2 or 3 or 4 or etc - goes straight to tab 1 or 2 or 3 or 4 etc

cmd+t - opens new tab
cmd+w - closes tab
