My current version of Firefox has become corrupt. When I try to download a new version with Internet Explorer or my current version of firefox it goes to 53% unpacked and then it comes up with file corrupt. I have had the same issue before and have solved it by using a linux CD to download a windows version and it unpacks and installs great. I now cannot find a place where I can specify which version I want and it insists on using the download for Linux which is useless for me.
