Get Firefox to ignore HTML 5 autocomplete tag setting?

Question

With HTML 5 there is a new attribute called autocomplete. If it's set to autocomplete=off, then the browser does not store the password.

How can I override this setting, short of modifying the source code of Firefox and recompiling it? Is there maybe a Firefox about:config option I am overlooking that I can toggle - an "ignore:autocomplete" or something?

Answer 1

The whole point of autocomplete=off is to provide some level of security for fields which require it. If a site designer has deemed that a field requires autocomplete=off, then there's a good chance that he means it. Why do you want to turn it off?

Short answer: No, there isn't a way to disable it. It's considered a security feature.

(by the way, autocomplete=off has been a feature in various browsers for ages... it may only have been made formally part of HTML as of HTML5, but it's been in use for a very long time, so I wouldn't consider it 'new')

There is an other way to make firefox remember the password thanks to Firebug: just change the value of autocomplete to "on", and save the form. Firefox will show the "remember" pop-up as usual.

Details are given here:

• install Firebug
• on the page with the faulty password field, open Firebug.
• use the blue mouse pointer in Firebug toolbar to select the password field on the Firebug HTML tab, you should have a field selected
• double-click on "off" to edit the value and change it to "on".
• Now, enter you login/password as usual in the page form
• when you hit "submit", Firefox should display the notification pop-up that allows to remember the login/password for that site.

Now, each time you are going to go on that page, firefox will autocomplete the login/password as usual.

The following bookmarklet makes all forms on this page autocompletable:

<a href="javascript:(function(){var fm=document.getElementsByTagName('form');for(i=0;i<fm.length;i++){fm[i].setAttribute('autocomplete','on');}})()">Autocomplete on</a>

Just put the above into an HTML file, visit it with your browser, drag the "Autocomplete on" link to your bookmarks toolbar, visit the page with the offending form, and click on the "Autocomplete on" bookmark to make form remember your entry.

The easiest way to do this is:

locate the nsLoginManager.js file under the "Mozilla Firefox" folder, such as:

C:\Program Files\Mozilla Firefox\nsLoginManager.js

locate the function

_isAutocompleteDisabled :  function (element) {
        if (element && element.hasAttribute(”autocomplete”) &&
            element.getAttribute(”autocomplete”).toLowerCase() == “off”)
            return true;

return false;
},

now change the first return from true to false such as this:

_isAutocompleteDisabled :  function (element) {
        if (element && element.hasAttribute(”autocomplete”) &&
            element.getAttribute(”autocomplete”).toLowerCase() == “off”)
            return false;  //This is the line of code that changed.....

return false;
},

Now save this change and restart firefox.

Answer 5

If you have Firefox you can install Greasemonkey and install this addon which re-enables autocomplete for the form. It's not perfect, but generally it works. For the sites that it does not entirely work for, you can craft a custom grease monekey script

Answer 6

The addon Auto-Complete On enables autocomplete only for login-related fields, so that credit card numbers and the like still won't be saved (at least in theory).

Given that this add-on is always on, that seems like a good idea. It is a no-restart addon, so in theory you could turn it on only when you need to with relatively easily.
