Microsoft Excell and Firefox not compatible?

Trying to get Excell to work properly on a friend's PC. after installing firefox it stopped working, you could get it up but are unable to enter any data. Any idea what it might be?

Thanks

 

Dont know how Excel and FF could coz problems in one another.

I dont think it has anything to do with FF. Try reinstalling Excel, and if that doesnt work, theres always Google Spreadsheets.

 

ok how about all the excel files existing, can they be transferred onto GSS?
