No PDF Download (w. Whitelist) 作成者: DerivedFunction

Modified/Experimental version of the <<No PDF Download addon by Merten Peetz>> that includes a options menu to whitelist several URLs. Please note: this may not be up to date compared to the original source. If something breaks here, please don't bother the original author <<Merten Peetz>>.

From https://addons.mozilla.org/en-US/firefox/addon/no-pdf-download/ :
While most PDF files can be viewed directly in the browser some PDFs will trigger a "Save as"-dialog or will be downloaded automatically. This addon views all PDF files directly in the browser. You can still save the PDF by pressing CTRL+S (or CMD+S) after viewing them.

Please make sure that the setting under Firefox > Preferences > Applications > PDF is set to "Preview in Firefox" in order for this addon to work.

Some web servers are misconfigured and don't tell the browser that a file is a PDF. In this case the file will still be downloaded even when this addon is active. If you encounter a PDF that is downloaded feel free to send the URL to the support email address so I can check if this it's a bug in the addon or just a server issue.
