Firefox does not allow to show PDF files in the browser, it downloads them directly.

I have seen multiple questions with a similar problem. The fix has usually been to go the settings / applications / change the PDF action to whichever they need. However, when I do that, the PDF entry is not present in the list of applications. Is there any way to find this entry again?

I’m on Firefox 99.0 on windows.

Thanks

Re-visit Settings/ Applications and re-confirm you do Not See -- Portable Document Format (PDF) -- in Applications; Don't look for just PDF....

Hi, just revisited and I can confirm that pdf is no there.

It does not appear either when I search for it in the app bar as you can see in the screen shots.

Cheers, Thomas

Hello, Firefox includes a PDF viewer so you can view PDF files within the browser window itself. If you can't open any PDF files with the built-in viewer, it may be caused by a Firefox extension. Disable them all to see which one causes problems.
