Post Context Unload Timeout (Magic xpi 4.9)
This setting determines the timeout of a context when the task page is switched to another page using the browser (such as Back, Forward, or a different URL). If the timeout has not expired, returning to the previous page reloads the last positioned context. If the timeout value has expired, the context for the previous task page is terminated.
The timeout value increments are defined in tenths of seconds. If you set the value as 0, no timeout duration is set and the context is cleared immediately.
Default: 1200 tenths of a second
Change effective: After restart
