How do I turn it off in the newest Firefox version?
Firefox doesnt use autocomplete, but it does remember your passwords, if thats what you mean. I dont know of a way to turn it off, theres no option to do so in the tools. Why do you want to turn it off, anyway?
No it has auto-complete. See look:
i think its this, open firefox and go to tools > options > privacy > saved form information
hope it helps
Doesn't Auto-Complete for me.
