My auto fill function seems to store e-mail addresses of people who have never logged into my computer; is that possible?

more options

I was logging in to Netflix and realized that the auto fill function of Mozilla was giving me as alternatives --besides my own e-mail address-- the e-mail addresses of four other people who have never used my computer to log in to anything (I know these four people). The same group of people also showed up when I tried to log in to facebook, but not in the webmail client of my workplace. Could auto fill pick e-mail addresses I used in thunderbird? If not, is there any other way for these addresses to show up in auto fill?

Many thanks for your help, all the best, Baki

HI btezcan and Baki, Thank you for your question, we can try to find out.

  • Are you using Firefox Sync, or are those users using other profiles?
  • And if you clear the cache, do these still auto complete?

I do know that Windows 7 has an autocomplete http://support.microsoft.com/kb/237553 but not sure if this would apply to programs, do you have this enabled?

Happy to further investigate :-)

"Could auto fill pick e-mail addresses I used in thunderbird? " No. Firefox isn't capable of using form-fill data from Thunderbird. Profile data (user data and prefs) are stored separately, and "never the twain shall meet". ... unless you installed addon that I am unaware of which allows data to be shared between Firefox and Thunderbird.

"If not, is there any other way for these addresses to show up in auto fill?" In addition to the questions that guigs2 asked: Same email addresses appear as "auto-fill choices" on both Netflix and on Facebook? Are those same 4 email addresses in Thunderbird, too? Are all 4 connected in some manner to your Facebook account? Sorry, I don't know how F'book works, but have read a lot about privacy vulnerabilities with their website and with their default user privacy settings. IOW, they are authorized at Facebook to access (say) a private area for your closest friends?
