FIREFOX Loading problem

[kmb``]

Hey, these passt few days ive been having a strange problem with my firefox, i dont remember if it was after the update or not but sometimes my firefox just wont load a webpage, amsn would not start ( unless i was previously connected to it then it wouldnt be a problem ) for about 15minutes. i have done no changes to my firefox besides the skin but i doubt thats the cause. I would also disconnect my internet and reconnect but yet everything still remains the same, anybody know what might be causing this problem?

thanks
