Hi Bow Great first step in a fresh reinstall, as that fixes most issues, although seeing as you still have the problem lets look into this in a bit more detail. As Yahoo Finance is somethingI have not used before I will need a bit more information if that is ok? The charts you are downloading, are they a seperate file which is then opened on firefox, such as a PDF? Or are they a direct link to another website from Yahoo? If it is a PDF then it may be something wrong with the file itself or a setting that needs to be changed with that file type. If its the website then we can do a bit more investigating. Just need a bit more info then we can get into this for you. Bradforth
