Firefox won't remember passwords when I restart my computer

more options

I got a new macbook air and installed firefox. I set it to remember my login info, and it will when I just quit and restart firefox, but if I quit and restart my computer, it will erase everything and I have to login on every website all over again. It's driving me nuts. Help!

Make sure you install Firefox properly and that you do not run Firefox from within the DMG (Disk Images) file.

Open the Firefox Disk Images file and drag the Firefox application to the Applications folder on your hard drive. You shouldn't double-click the Firefox application to run it from the Disk Images, but instead drag it out of the DMG folder.

You can check that you aren't clearing important cookies.

  • using "Delete cookies and site data when Firefox is closed" keeps cookies with an allow exception
  • using "Clear history when Firefox closes" to clear cookies clears all cookies including cookies with an allow exception you may want to keep
  • Options/Preferences -> Privacy & Security
