Absolutely. For the longest time I had this extension called "Comment Save" which saved anything you typed in a textarea. It doesn't seem to exist anymore, and I haven't been able to find a good replacement. I would also much rather have it in the browser than giving full permission to some third party. The back button in Chrome sometimes help but I still lose long messages all the time.
