I just noticed that when I hover with my cursor over a link, I don't get the url. I tried in maximized (full screen) and normal mode, and it doesn't show up in a popup or in a bottom bar as it does on Firefox. It's a bit annoying of course. I know about snowleopard's behavior, has Apple changed their stance or is still an external plugin the best solution?
If you enable the status bar you can see the target URL without plugin. You might prefer the plugin still though.
To enable, go to the View menu and click "Show Status Bar".
