Stop downloading all my PDFs!
No matter which option I select for opening a PDF (Open with Firefox, Open with Adobe Acrobat, or Save File) the PDF automatically saves itself to my Downloads folder. I do not want this. I don't want to constantly have to go in there and delete all these PDFs that I only needed to view once. Is this a feature or a bug? If it's a bug, please help me fix it guys. If it's a feature, that was a terrible decision from the Firefox dev team. I can't be the only one annoyed at this??
Firefox may be set to automatically download PDF files instead of opening them in the browser. You can try changing the settings to preview PDFs in Firefox or resetting Firefox to its default settings. If the issue persists, there may be a configuration issue on your computer and you should seek assistance from a technical support specialist.
You need to enter about:config in the address bar and change the following preference to true. browser.download.start_downloads_in_tmp_dir
