Before the search engine change to v57, I used to use an Extension called "Textarea Cache." It still works on Waterfox. If you lose text from an entry box & it isn't in the clipboard, Textarea Cache still saves it for recovery. Is there any extension in the current FireFox that does the same function?

I lost so many important extensions when FireFox upgraded that I mostly use WaterFox these days despite the better security of Firefox. Too many lost critical extensions that have no work-alike in post v.57 Firefox - like Classic Theme Restorer, All-in-One Sidebar, Vertical SideBar, etc.
