As the title explains, Firefox clears my cookies whenever i open it. not when i close it, but when i open.

the option to clear cookies on close is off, i have no clue why it's doing this, i know it's not an extension or a program. ( at least i hope it's not )

thankfully it always makes a backup but i really don't want to have to through the files and remove the .bak every single time i wanna go through the internet. any advice?

If Firefox clears data when opening then this can happen if Firefox failed to close properly the last time and didn't finish clearing up data. When Firefox notices this on the next start then it will complete all tasks that weren't finished on the previous close down.

Use one of these to close Firefox if you are currently doing that by clicking the close X on the Firefox Title bar, especially if you have multiple windows open to prevent losing tabs in unnoticed windows.

  • "3-bar" menu button -> Exit (Power button)
  • Windows: File -> Exit
  • Mac: Firefox -> Quit Firefox
  • Linux: File -> Quit

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

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
  • clearing "Site Preferences" clears exceptions for cookies, images, pop-up windows, and software installation and exceptions for passwords and other website specific data
  • Settings -> Privacy & Security
    Cookies and Site Data: "Manage Exceptions"
  • Settings -> Privacy & Security
    Firefox will: "Use custom settings for history":
    [X] "Clear history when Firefox closes" -> Settings
