Update:-
'Borrowed' my friend's lappy this morning, and for the benefit of those like myself who are lacking in the IT department, I did the following:-
Tried to start Firefox both with the desktop icon, and also in the 'all progs', but no joy. Tried control, shift, escape, to see if it was running, it wasn't. Deleted the program via the control panel. Reinstalled it again, 'Start' told me a new prog had been installed and gave me the option to start it in safe mode. In safe mode I chose to start without any add-ons. Hey presto that seemed to do the trick, and strangely all the favourites etc., were still there. However the home page in Firefox had been changed to 'incredimail'.....yes I know you don't have to tell me.
Thank you everyone who once again have come to my aid. Special mention and thanks to DaiNasty who I spoke to last evening and who solved my Disk Cleanup problem. Must add that it is very strange to put a voice to someone you have only previously known as a nom de plume(?) Pleasant experience to be sure.
