Hi people, I've been using Firefox 220.127.116.11 on the Mac without any real issues (other than some smudgy tab titles which had been described in other threads). There is, however, an issue with the way FF handles PDF files. Whenever I select 'open with preview' , FF saves a copy of the PDF file on the desktop -- even though I chose just to open it (I know that a temporary file should be created somewhere, but there is no reason for a copy to be saved to the desktop). Do you know of a way to avoid this problem? Many thanks, Am.
