The un/folding status of Interaction, Toolbars and Languages in the sidebar is supposed to be remembered using a cookie. In fact it appears to be random. I want all of them open, because i use all all the links all the time, but they fold randomly when i move between articles.
It also makes me think - why a cookie and not a preference? Using a preference is impossible for anonymous users, but if user who has an account opens it on a different computer and sees his sidebar not the way he's used to, it's quite confusing.
While you think about fixing this, think about [[bug 23497]], too - remember that it's more important to show the links than to hide them.
