Hi, for some reason I cannot figure out, TFF 7450 on my PowerBook will no longer open PDF files - when I click on a pdf link nothing at all happens. In Preferences PDF's are to be previewed in TFF but nothing happens. It used to work fine but I think has stopped working after a crash. Thanks for your help.

   Hermano, which version of TenFourFox do you have? Click 'TenFourFox' in the menu bar, then 'About TenFourFox'. If it's not 45.6 or 45.7, please update to the latest version first.

   Then, check that 1) Preferences>TenFourFox has 'Use built-in PDF viewer' checked and 2) Preferences>Applications has 'Portable Document Format" = Preview in TenFourFox (just filter/search for PDF).

   Then try this test pdf which should work:

   Hi Chris,
   TenFourFox version is 45.7 (it did the same in 45.6)
   Preferences are set as you suggest - in fact these settings have not changed.
   I tried your pdf test link above and I get a blank browser window.

   The thing is, it used to work flawlessly then recently it just stopped. That's when I replaced v45.6 with 45.7 and there was no change.

   Thanks for your help.

   Okay, this is weird. Try this: Click Help>Troubleshooting Information, then "Restart with Add-ons disabled".

   Your link above works but this one doesn't it gives a download confirmation badge no matter if use built-in PDF viewer is checked or not. Curiously when use-built-in PDF viewer is unchecked with your link the file is downloaded without confirmation.

   That's because that link (degoogled: http://pdfstream.manualsonline.com/6/64abee20-5ce2-4a37-a7a4-e48e0d...) generates a MIME type of application/octet-stream which is just "generic binary." The in-browser PDF viewer only opens for application/pdf and related MIME headers. Having the browser open the PDF viewer for anything ending in .pdf is actually problematic for a number of reasons I won't get into here, but suffice it to say I don't consider that a bug.
