how to restore the red/yellow/green buttons in safari

There was a problem with my mousepad last night and it was sending the cursor all over the place. Its corrected itself now but something happened while it was doing this. I was trying to close down safari (and fighting with the cursor) and the bar at the top of safari disappeared. along with it went the red, yellow and green buttons.

I have no idea how to get them back. I have tried to customise the toolbar but thats not the solution.

when safari is in full screen i now have just the address bar and bookmarks bar.

I'd really like to restore these buttons and get the title bar (with file, view etc) back. To access those currently i have to hover the cursor at the top of the screen. Its very annoying not to be able to see the time, remaining battery etc.

If anyone has any suggestions i'd really appreciete it!

Thanks
