[Closed] Alert when close a Specific Tab



Start with an example. 5 mins ago, I write almost important content of 500 words in a form of a website and during switch another tab, I accidentally close my form’s tab and lost my all content. It did happen with me a couple of time. So I believe this feature will help others a lot.
Need a feature which will give me an Alert before close my tab, if I write something unfinished or didn’t submit.

Thank you,
