I recently got a new laptop and firefox has been acting odd on it. I typically have two windows open: one regular, one private browsing. Usually this setup is fine, but occasionally when I wake my computer up, it has inexplicably closed my private window while leaving the regular one untouched. It only ever does this to the private window, and after the computer has gone into and woken up from hibernate. It doesn't always do this, but I find it strange that it would do it at all. Has anyone else ever had this issue and know how to fix it? Thank you to anyone who can help.
