Hello, I'm a student from Brazil, I use IceWeasel recently and I wonder if anyone can help me... I'm new at using IceWeasel, and I run it on a simple debian network with user logins... When a user logs off without closing IceWeasel, or the session crashes, or the machine is turned off then on, in the moment I try to open IceWeasel it appears on a pop-up that is already open, but it's not ! I know that's called the lock file, or something like that, and I wonder if I can disable this feature somewhere, or how I do it with a shell? Or is it a bug? Please help me! Thanks already !!
