Fire Fox Help

[iggy880]

I know we have a technical section, but I also know the traffic there is less than how much I care for anime(I like the idea but don't care for it) so I'm posting this here. Anyways, when I got Fire Fox, I customized my bar, and put certain icons like favorites and new tab up there, and they stayed, but recentyl, they've gone away, and when I put them back, they're gone when I close, and then reopen the window. I't really bugs me since I like having them their for ease, so any help, at all, is extremely welcome.
