This can be caused by clearing the cookies via Delete browsing, search and download history on Firefox.
You can try to exclude the cookies to see if that helps.

You can let all cookies expire when you close Firefox to remove unwanted cookies and keep the ones with an allow exception.

  • Tools > Options > Privacy > Cookies: "Keep until": "I close Firefox"

If you use Delete browsing, search and download history on Firefox to clear the cookies when you close Firefox then Firefox also tries to clear the cookies from plugins like Flash and starts a plugin-container process with the Flash player and possibly other plugins as well for each cookie, so that can add extra time if there are a lot of cookies to remove.
