Can I disable Google Chrome Autofill ONLY for localhost?

I'm a developer and it's VERY annoying having Chrome suggest all my personal address information in forms one web sites I'm developing on running on my local machine. Is disabling Autofill on localhost, or a domain, or an IP address possible? I'm not seeing anything in the advanced settings.

Answer

I recently answered another question with the same requirement of customizing features of Chrome (and also inspired from @Paul).

NOTE: This solution allows you to block a specific IP address or list
of IPs, without having to load any additional library and no
additional scripts in your project. Fact often you may have blocked
all Javascript features, but the control "noautofill" follow operating,
avoiding collisions with other libraries, allowing also you have a real
recognition of the consumption charge and rendering time, and this can
translate into savings of time debugging day to day, on different web
projects.

Create a Chrome extension that uses the "match filter host" of the Chrome API, and filter your custom IP host or namehost. Then set the attribute autocomplete to off for all "input" and "form" tags.

We proceed with these steps:

• Create a new folder named ex. noautofill




• Create into our new folder, a new file named manifest.json and add this code inside:

{
  "name": "No Autofill",
  "version": "1.0",
  "manifest_version": 2,
  "description": "No Autofill.",
  "content_scripts": [ {
      "all_frames": true,
      "exclude_globs": [  ],
      "include_globs": [ "*" ],
      "js": [ "script.js" ],
      "matches": [
                   "http://192.168.1.100/",
                   "http://127.0.0.1/",
                   "http://10.0.1.100/",
                   "http://localhost/",
                   "http://wp.local/",
                   "http://192.168.1.100/*",
                   "http://127.0.0.1/*",
                   "http://10.0.1.100/*",
                   "http://localhost/*",
                   "http://wp.local/*"
                    ],
      "run_at": "document_start"
   } ],
  "permissions": [ "tabs", "http://*/", "https://*/", "https://*/*", "http://*/*", "contextMenus" ]
}

• In our new folder, create a new file named script.js and add this code inside:

(function(){
    chrome.extension.sendRequest({
        autofill:'off'
    },function(){
        var inputnodes = document.getElementsByTagName('input');
        for(var i=0;i            inputnodes[i].setAttribute('autocomplete','off');
        }
        var formnodes = document.getElementsByTagName("form");
        for(var i=0;i            formnodes[i].setAttribute('autocomplete','off');
        }
  });
})();

• We go to Chrome's menu » Settings » Extensions




• Now we click the button "Load unpacked extensions"




• Finally we mark our folder and click on the open button.

This is the result:

This system is very simple, and you can customize the file script.js with your own control code. In the future you may add other scripts, CSS, configuration pages, etc. Remember that every time you will make changes in the file script.js you should reload the plugin with CtrlR.
