The downside to this of course is that if you need only simply "view" several files a day, each file you view adds to the clutter of the "download" folder on your computer. Of course, when you have a mix of necessary PDF downloads and unnecessary "temporary" downloads, the result is not optimal.
On the other hand, Firefox does have a plugin for Intel or PowerPC macs which will enable inline PDF viewing, a great tool if you view a lot of PDFs in a day. Simply go to https://addons.mozilla.org/en-US/firefox/addon/7518 to install the plug-in for Firefox.
