I've got an XP machine with Acrobat Pro 6.0 installed and it worksforme. Just for kicks, try starting Acrobat first, then go into FF and try to load a PDF file.

Whenever you link to a PDF using Firefox 1.0 (XP), FireFox does launch the image (or begins to), but then it lapses into Not Responding and you have to hard close using CTRL-ALT-DEL. This happens every time.

jfwerb@shaw.ca: I don't know if it is possible for Acrobat Pro product line, but maybe you should try to upgrade.

I can confirm this. Firefox tries to open a PDF using the Adobe browser plug-in, which just opens Acrobat within the Firefox window. Everything works fine until you either try to go back to the previous page or close the browser, then Firefox hangs. Happens every time. The only workarounds I know of: either save the PDF to the desktop and open it directly from Acrobat, or disable the PDF plug-in so that Firefox will send it straight to Acrobat. I'm using Firefox 1.0.1, Windows XP (Home and Pro, same crash on both), and Adobe Acrobat Standard 6.0.

This is not a Firefox bug - I found the solution on the Adobe website. The problem is caused by excessive temp .pdf files, which hangs up the Reader. Go to this web page on the Adobe site to fix it: http://www.adobe.com/support/techdocs/329444.html Worked for me!
