Which "Autofill" are you using in Firefox 4.0?

Firefox doesn't have a built-in "autofill" function, it has "auto complete" which wouldn't display a message such as that.

Thanks for your answer. I clicked on Autofill, Edit and found that the Autofill I use is a Google Toolbar option, DUH. Can you tell me if I can and how to find/install "Autocomplete"? I want something to fill in forms, petitions, etc.

Yes, I know Autofill is a Google toolbar feature, but it worked in Firefox prior to 4.0, s something has been changed (by Mozilla).

Any solution?

After upgrading to Firefox 4.o my Google autofill also stopped working. I removed the Google toolbar from my addons and reinstalled the Google toolbar. My autofill function is working again.

What a mess, oh what a mess has Version 5 of Mozilla Firefox done to my toolbar. No autofill no nothing. Come on Mozilla sort this out or I shall not be using you as my browser. might revert to Google Chrome

My Firefox Auto-filled worked so well until a couple days ago when it disappeared from my toolbar. When I right-clicked on my toolbar & chose Customize, Autofill didn't even appear in the add-on box. How do I get it back? I can't even find it in Control Panel>Uninstall, so I can't re-download it. Even in Computer, I get no results, but when I right-click on a page, it shows me the options to autofill. But I can't get to the Settings for autofill. It's very frustrating.

The Google Toolbar 7.1.20110512W version works in Firefox 5.0 by using the Compatibility Reporter extension, I tried it myself due to the large number of postings about GTB problems.
