Tab Dial од Shineblind

A New tab page that shows bookmarks and with a Current Tabs section, you can also click the extension icon to see open tabs, made with touch screens in mind.

The new new-tab page syncs your bookmarks with your "Shortcuts" bookmarks folder, so you can copy your favourite bookmarks there. In the top right of the new tab, click the cogwheel to change the background.

You can double touch-tap on bookmarks to open them in the background as well as middle mouse, you can also middle mouse the open tabs to close them.

You can also disable the whole new tab page if you wish and only use it for clicking the extension button to see all your open tabs, it also shows the thumbnail of the tabs, you can do this by going to Settings -> Home -> change "New Tabs" to "Firefox Home Default".

This was mostly made for myself, and because I saw a lack of extensions that simply show open tabs as thumbnails as well as being touch screen friendly. Made with a little help from my friends (or a lot).
