Is anyone else having Firefox problems?

Basically, every time I log onto Seibertron I keep getting told that firefox has encountered a problem and needs to close. It doesn't matter how long I've been on my laptop (seibs is usually the first site I visit), and this is the only site it happens on.
Does this happen to anyone else, or does anyone know of a way to solve it? (I'm not very technical, so any computer jargon in leyman's terms please
)
Oh - and its the latest version of Firefox that I'm using.
