Apple - How do I close all tabs on Safari for iPad after the app crashes

• Force-quit Safari (double-tap the home button, then tap and hold on the Safari icon until it shakes, then tap the red minus sign).

• Go to Settings > Safari.

• Tap Clear History.

This should clear out all open tabs.

I struggled through this last night and stumbled upon a solution. Go to Settings > Safari. Turn on private browsing. It will ask you if you want to close all tabs before turning on private browsing. Touch 'yes'. Next turn private browsing back off. Voila! The browser works again!
