Hello Eric,
Thank you for your investigations!
I think I now know what caused the issue (sluggish opening of the local pdf file) and have a solution for anyone else who may find these notes.
Crudely speaking the FireFox default pdf browser "PDF.js" seems to have to read the full file contents before it can render it, thereby causing the initial delay (about 10 seconds for my 1200 page file).
The problem was solved by installing the free pdf viewer from
http://www.tracker-software.com/product/pdf-xchange-viewer (Windows only), and then selecting Tools->Options->Applications tab from FireFox and setting the "action=Use PDF XChange Viewer (in FireFox)" for the "Content Type = PDF". I think this option should also work using the Adobe Viewer plugin, but it didn't work on my computer.
The pdf file now opens instantly in a FireFox tab at the correct page number.
Thanks to all!
Regards,
Bob
