Contents

Background

Firefox 2.0 introduces a built-in Session Restore feature, allowing the user to continue browsing from where they left off if browser restarts. This preference controls when to store extra information about a session: contents of forms, scrollbar positions, cookies, and POST data.

Possible values and their effects

0

Store extra session data for any site. (Default starting with Firefox 4.)

1

Store extra session data for unencrypted (non-HTTPS) sites only. (Default before Firefox 4.)

2

Never store extra session data.

Recommended settings

Leaving this preference set to 1 will avoid re-submitting data to secure sites — such as banks and online stores — and prevents duplicate transactions from taking place. Use caution when setting this preference to 0.

First checked in
