Disable password autocomplete in Firefox
Handy little trick to make Firefox behave in a more security-conscious manner
Saturday, December 5th, 2009
Firefox seems intent on autocompleting password fields, whether you want it to or not, which is not good for security if you’re building a web app with “old password / new password” functionality.
Luckily, I’ve found a way to trick it into not doing this.
Simply place a hidden password field, with no name, at the start of your form:
<input type="password" style="display: none;"/>
This seems to trick firefox into thinking that this is the main password field, but as there’s no name it a) doesn’t get set and b) doesn’t get submitted.
Great
