Suddenly I’ve realized, that the message “Are you sure you want to navigate away from this page? The changes you made will be lost if you navigate away from this page.” is totally gone. I and my users (Editors in our multi-author blog) can’t get this message anyway they try. How can I restore this alert, to warn users to save their changes?
Doesn’t work at Firefox and Chrome.
Especially on Macs, where is default “go to previous line” hotkey binded by Firefox as “go back in history”. And some editors went back during editing posts….
