All of that information is stored in your Firefox profile folder on your computer. If you want to make a copy of that data or perform a backup, see Back up and restore information in Firefox profiles for more information.

Hope this helps.

Thanks Wes. I'm looking for the setting that "saves" my login ID, that in Facebook "saves browser". There has to be a setting that erases that info when I log out.

Thanks

Ed

A detail like a website remembering you (log you in automatically) is stored in a cookie.

You can use these steps to make a website recognize and remember you:

• create a cookie allow exception with the proper protocol (https:// or http://) to make a website remember you
• use "Delete cookies and site data when Firefox is closed" to let cookies without allow exception expire when Firefox is closed
• Options/Preferences -> Privacy & Security
  Cookies and Site Data: "Manage Permissions"

In case you use "Clear history when Firefox closes" or otherwise clear history.

• do not clear the Cookies
• do not clear the Site Preferences

• Options/Preferences -> Privacy & Security
  Firefox will: "Use custom settings for history":
  [X] "Clear history when Firefox closes" -> Settings
• https://support.mozilla.org/en-US/kb/delete-browsing-search-download-history-firefox

• clearing "Site Preferences" clears exceptions for cookies, images, pop-up windows, and software installation and exception for password and other website specific data
• clearing "Cookies" will remove all selected cookies including cookies with an allow exception you may want to keep
