So PDF's can no longer be set to open in Adobe, but it now requires clicking before the document opens in Adobe. No setting whatsoever can change this. Is this a permanent setting? Will have to move to another browser now. What a hassle. Got to move bookmarks, set up home pages etc. Ugh. Bey Firefox....

Firefox Automatically Opens Print Preview When Opening a PPT/PDF

I am experiencing an issue with Firefox where the Print Preview window automatically opens whenever I open my PPT/PDF file in Firefox.

As shown in the attached screenshot, Firefox immediately displays the Print panel instead of simply opening the document for viewing. I have to manually click Cancel or press Esc every time.

I did not intentionally select the Print option, and I would like Firefox to open the document normally without automatically launching Print Preview.

Could you please investigate this issue and let me know how I can prevent the Print Preview window from opening automatically?

Adobe auto updated. The ability to choose where a PDF is opened or downloaded is now missing. Completely makes FireFox unsuitable for what I do.

I did redo all the settings to 'ask before'. Refreshed FireFox. Tried changing it in the popup where I choose what to print.

What do I need to fix?

When Fidefox updated to 157, it kept all my settings, but it will not allow my windows default PDF viewer to save and open PDFs automatically. Instead, it uses the Firefox PDF viewer - which has improved, but it is not what I would like. I have reset my handlers.json along with trying to force it via about:config. Nothing is working, and it is a hassle.

Why does Firefox open PDF files directly instead of asking me to choose between opening them in Firefox or in my default PC application (Foxit Reader), even though it is set to "Always ask"?

Version 157.0 (64bit) has updated and resizing has caused issues. Previously, on my laptop screen, when I was viewing pdfs in browser I would navigate to the Tools dropdown and view the document properties at the very bottom of the dropdown. Before the update, all of the menu items fit without needing to scroll (when the window was fullscreen). Now, i must scroll in the dropdown to access Document Properties. The update resized the menu, making it longer and now it overflows. Please consider resizing back to original size or allowing users to adjust the dropdown menu.
