help for offline view

[ansari]

I'm a new user of firefox (1.5.0.6) .
I've used I.E.6, but now firefox is my default browser. My OS is winxp-pack2 .
I thanks much for speed and facility,but it seems history sessions has problem or inefficiency in firefox. it doesn't cash viewed pages for offline review.
it cashes sometimes but soon later dosen't show pages in offline mode.
is this a common thing with you guys?
I try anyway ( change profile - reinstal - go offline mode before disconnect of internet ) but any of them didn't solve my problem.
can anyone help me?
