We have a business to business website that we use which we download PDFs off of. We have been using Firefox to download from this site for probably 3-4 years. As recently as yesterday, we began having file permission issues with the PDFs that we are downloading. When the file is downloaded and you right click and open "get info" the file says that "everyone" has "no access". This is definitely a Firefox issue as we have tried it with Chrome and Safari and neither one has the same problem. We are running on a Mac platform and have Firefox 24.0.
