I usually copy-paste longish things to the text editor (or at least to clipboard) to avoid data loss in case the webapp crashed / browser crashed / HTTP request failed / I mistakenly pressed backspace when out of the textarea (which navigates to previous page)

It happens rarely but when it happens, it hurts.

Try the Lazarus extension. It keeps a history of form fields. It saved my butt more than once.

A browser extension I didn't know I wanted. Keeps history of textfields when I navigate away, and gives me an option to restore.

There are some, like [1]

But I use many browsers, webapps reset the forms contents with JS etc. It's complicated.
