Rated 2 out of 5 stars
I was looking for autosave after couple of big edit losses on a Wiki.
Autosave feature in this extension needs some work. Each text area has to be saved, and autosave turned on after that. I need it to be turned on by default.
For now, I opted for Textarea Backup user script.
Oh, and I'm not sure what "Once you set the options the first time" was referring to. Preferences seem to be unavailable.
