Where on Windows hard drive does Firefox temporarily store PDF files that I open from websites when I have Adobe Reader configured as the default PDF reader?
I have Windows 7 and Firefox 19.0.2. I see that every time I open a PDF file from a website, it prompts me to either save the file or open it with a program (defaults to Adobe Acrobat Reader). If it is the same file name that I keep opening up over and over, it appends an incremental number to the end of the file name. To me this implies that it is download the file to a temporary location and then opening it in Adobe Reader. Where is Firefox storing these files and how can I be sure that they are being deleted regularly? I don't want these files to be kept on my local hard drive after I close the file in Adobe Acrobat.

Files that you choose to open with an external program are saved in your temporary folder. To open it, click the Windows logo orb on the taskbar, type %TEMP% in the search box, then press Enter.
You can clean out temporary files in Windows using the Disk Cleanup utility. The program can also be scheduled to perform cleaning tasks automatically without prompting.

That shouldn't be happening. If you try to download a file that's already in your temporary folder, it should simply open instead of being downloaded again.
I don't know what could be causing it though. First, try upgrading to the latest version of Firefox. If nothing else, your system will no longer be vulnerable to the security holes in the version you're using.
If this is happening with different files on different web pages then you may have an extension causing this behavior.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
- Do NOT click the Reset button on the Safe Mode start window or otherwise make changes.
