My saved usernames and passwords used to autofill. This stopped all of a sudden and the box to save logins is unchecked and won't allow me to check it. Also, I had checked the box for the history to delete when Foxfire closes but now the box is unchecked and won't let me check it.

Hi, I do not know myself but someone will take a look at this later.

Though I suggest saving passwords, profile, bookmarks and reinstall but not sure if your suppose to go to FireFox ESR or not.

FYI : Please be advised September this year support by Firefox ends for Vista and older browsers https://support.mozilla.org/en-US/kb/firefox-no-longer-works-some-versions-windows-xp

Make sure you do not run Firefox in permanent Private Browsing mode (Always use Private Browsing mode; Never Remember History).

  • Options/Preferences -> Privacy -> Firefox will: "Use custom settings for history"
  • Deselect: [ ] "Always use Private Browsing mode"
