In a netshell, in FF 19 beta I can only now create PDF's if I do it from the Print Preview Pane.
In the previous FF update prior to FF 19, PDF printing was sporatic, BUT I could usually print to PDF if after choosing the fiename to print to, and minimizing Firefox.
It appears that the Dialog "Creating Adobe PDF" is being blocked and hidden.
I just found out, I have to do the mimimize Window thing to when using Print Preview.
Select Adobe PDF'
Immediately mimnimize the window after checking OK
Windows+m may minimize. Still experimenting.
But at least, so far it works.
I MAY have a better solution. Not 100% sure yet. Make sure the Adobe Creating PDF window can appear without Firefox on top of it. Move FF out of the way before you print.
It will also work without doing the print preview first.
SO, just move FF down 3/4 of the page before you hit print.
The problem seems to have ended after the latest Acrobat X and Firefox updates. I had the same problem yesterday, but for some reason today, my prints are going directly to the Acrobat X driver. I will keep my fingers crossed that this issue doesn't recur. I was having problems with Firefox crashing whether or not I used print preview. Your suggestions were helpful, and I appreciate your help with resolving the problem.
Firefox updated today and I checked for adobe updates and there were some. My problem still persists.
So, as I said move the top of Firefox down about 2/3 of the page and then print if it happens again.
Unfortunately, while the NYT pages cooperated, some of the other pages did not. I will follow your advice and hope they decide to fix the problem. I also have an issue with Adobe not printing web captures from comments loaded from Disqus, but I think it's an issue with how Disqus handles Acrobat as a web page. Grrr...I had hoped that this was done!
Yea, I know it does appear to be a hit or miss situation and, for me, mostly miss. The "Creating Adobe PDF" window gets really burried.
Sometimes it never, ever completes, but the document does. Other times it will appear just as you Kill Firefox. Somtimes the docuament names are even wrong.
In short, it's really messed up.
There is Firefox doing things, Windows doing things, Distiller doing things and they really all need to be on top, but not on top of each other. I think Firefox is monopolizing the desktop.
It's painfully obvious that the PDF prnter file dialog should come to the front automatically and it doesn;t. It hasn't for a while. Again, Firefox wins.
Notice that when you move some of the Adobe dialogs, the Firefox screen underneath leaves holes.
