Fairly sure its only some encrypted pages that have problems with firefox and as far as I am aware microsoft isnt encrypted!
That is a bit random, although i know that sometimes my symantec update goes a bit funny and I have to prod it into action but microsoft updates are normally gd.
Know any1 else in the land of OZ that is connected to the internet and if so, try it on theirs maybe???????
Gd luck
