My first reaction was: I guess I'm not responding after all. Then it occurred to me, DevTools must have my data somewhere, right? Lucky for me, the answer was yes.
There might be easier ways, this is what worked for me:
- open DevTools
- go to the "Network" tab.
- look for the row with the method POST.
- If you don't see a POST row, try refreshing the page. With any luck you'll get a repost confirmation dialog, giving you some hope that your data is still around. (You'll want to allow the data repost)
- click on the POST row, and scroll down till you see "Form Data". If you've gotten this far, hopefully you'll find your data in clear text and able to be copied.
