You can try to check the entries with this extension: Form History Control: https://addons.mozilla.org/firefox/addon/12021

It is possible that there is a problem with the file that stores the "Saved Form" data. Rename or delete formhistory.sqlite (plus formhistory.sqlite-journal and formhistory.sqlite.corrupt and formhistory.dat, if they exist) in the Profile Folder in case there is a problem with the file that stores the "Saved Form" data. This will remove all saved form data, so you may want to rename formhistory.sqlite to formhistory.sqlite.sav or move the file to another folder in case you need to recover some saved data.

hi, thanks, i will have a look at installing that. i was wondering, though, if the word "null" has any significance in this context? unlikely to be just random

i noticed that this was a 'value' in a 'field'. so did a Google search for 'field value null', & came up with http://databases.about.com/cs/sql/a/aa042803a.htm : ..Users new to the world of databases are often confused by a special value particular to our field – the NULL value. This value can be found in a field.. NULL is the value used to represent an unknown piece of data.. looks like the database for autocomplete has “null” for my middle name?

In my case, I have a field admin_phone_extension that is getting filled in with the saved "email" field on a specific page.

I can verify this by logging in to our application with the form history control open, see the "email" field saved, delete that email field only, then navigate to the page in question, the admin_phone_extension is blank.

Log out then log in and navigate to that page without messign with the saved history, adn the admin_phone_extension field is filled in with the email.

the markup for the field is: <input name="admin_phone_extension" value="<?=(isset($advertiser['admin_phone_extension'])?$advertiser['admin_phone_extension']:<em>)?>" style="width:35px;" type="text">

so why it is getting autofilled with the saved contents of the "email" field is beyond me.

One of my coworkers has a problem on a gaming site where every time she logs in and goes to edit her account on http://taint.rtgc.org, it fills in a field named "phone" with the value from a field named "login"

And this happens EVERY TIME she goes to that site.

We can possibly provide more information in private emails, as both of these issues happen behind a login which we cannot publish publicly.

Yesterday I was filling out a form on line starting with my name. The auto fill function gave me the option to click on my name or two other names. One name had Saudi Arabia next to the name and the other gave the name in Chinese and the country, China. What are these? Might I have security issues?
