There are several issues that have to do with losing data by hitting the back button, anchor in overlay, and related. This is the place to link them all.
#1636992: form.js' formUpdated event is unreliable/incomplete
#153313: ckeditor input is lost when using the browser's back button
#1542472: Clicking on multiple anchor links while in overlay causes a page refresh potentially causing form data to be lost
#655388: Many ways to lose data on form input in the overlay
#193799: Warn before losing changes (eg: blocks and menu admin pages)
#504378: Auto-save draggable forms
In contrib:
#1637404: Improve Drupal.behaviors.formUpdated
There might be some duplicates up there that need to be closed. These are old issues so I'm not quite comfortable closing everything for one.

Wim LeersThe Drupal site I use most is d.o. I think we've all lost a long issue comment at some point.
Hence I agree this would indeed be valuable to have.

All the related issues are closed except one so I am closing this issue. Reopen if this is still needed.
