Are there any kind of restrictions in place on your computer? (Sometimes employee computers have locks on them that make them unable them to instal anything)

NOTE: This may sound silly, but are you sure that you are not pressing a 'Back' or 'Cancel' button by mistake?

Thanks Strongwind but updates have never been a problem...till this one...my own PC...no restrictions that I know of and all i press is next or update or download....just downloads then says installing ..then goes to strongly suggest... then tries to download and stays continuously blue line going from LtoR. I can not give picture of what is not going on as the box minimises as soon as I try. but thanks for trying... any more suggestions welcome.

I have managed to solve this problem by Downloading direct from FF web downloads. Still the 6.0 opens two of the same page but it is working smoothly now at least.
