Details like websites remembering you (log you in automatically) are stored in a cookie.

  • Create a cookie 'allow' exception to keep such cookies, especially in case of secure websites and when cookies expire when Firefox is closed.
  • Tools > Options > Privacy > "Use custom settings for history" > Cookies: Exceptions

In case you are using "Clear history when Firefox closes":

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

Note that clearing "Site Preferences" clears all exceptions for cookies, images, pop-up windows, software installation, passwords, and other website specific data.

Clearing cookies will remove all specified (selected) cookies including cookies with an allow exception that you would like to keep.


Note that your System Details List shows multiple Flash plugins.

  • Shockwave Flash 15.0 r0
  • Shockwave Flash 14.0 r0

You can find the installation path of all plugins on the about:plugins page.

You can check the Flash player installation folder for multiple Flash player plugins and remove older version(s) of the plugin (NPSWF32) and possibly (re)install the latest Flash player.
