Since updating to Firefox 4 I've had a problem:
With Firefox 3.x I could start it without a Internet connection and almost all of my open tabs were still loaded. With this I was able to read my open sites in the train where I have no Internet connection.
However this does not work in Firefox 4; if I launch Firefox 4 I see all my open tabs but the content is not available. It seems that the new version tries to refresh all tabs on startup.
Is it possible to disable this behaviour?
