Prompt to leave page

Is there a feature on ATS to prompt before you leave a page?

If on firefox or chrom is there a setting that needs to changed?

If non exist. I think it would be a fantastic idea * and releaving of stress and ragequit* (i imagine many members don't bother posting after a while because when they type something they are afraid it will erase on them)

Most sites like facebook has this feature.
So that is why i am wonder if it is the browser or ATS itself. Even many AD websites who use far less features use this and even have it intergrated to the point where it prompts differnt windows.

Anyways, Could you add this simple function and save a multitude of headaches as well as possible bring members back? ( not speaking for myself but i imagine a couple look at this secenario and say. Thats retarded, and leave)

Thanks very much for looking into the issue.
