Mobile Safari's limit is 500 tabs, including on the iPad. When you then try to open another tab, the options are: * close tabs not opened in the past month * close all tabs * cancel It's not a big dialog box. If you misclick "close all tabs," there's no "are you sure?" confirmation. You can recover 200 or so. I've filed feedback / issue / bugs about this.
