Disable the Firefox Android PDF Viewer

[Annoyed1]

Firefox Android now opens PDF files in the browser.  This is not something that I want.  Is it possible to disable this "feature"? 

If the answer is "move to nightly builds and muck about with about:config" then I will be uninstalling and canceling my Firefox subscription.

I agree, it is incredibly annoying! At least add an "Save as" button so we can save to file. The problem is when it is fancy URLs, not just something ending in *.pdf

Yeah, I'm pretty tired of the forced pdf viewer in firefox at this point. Make it an on/off toggle in the settings.

Agreed here. It also makes downloading pdfs so difficult. I don't want to be stuck in my browser while some file is downloading. I just want to click "download" and forget. I want to see the progress of the download in case it fails.

Current pdf functionality of Firefox on android offers none of that. It's unusable. I have to resort to launching chrome just to download a single pdf file.

Meanwhile it is possible to make Firefox usable again by setting pdfjs.disabled to true

This is beyond annoying.  The Firefox PDF viewer does not work!  It produces a jumble that is totally unreadable.  I'm attaching two files; the first is a pdf file downloaded and displayed in Firefox on a Windows 11 machine, the second is the same pdf downloaded and displayed on a Samsung Galaxy S6Tab tablet.

I have used Firefox as my browser of choice since its inception.  This "feature" now has me considering if I should switch to Chrome... which, incidently displays the pdf file just fine on the pad. 

Well, it appears I can't attach 2 files so the one you will see is Android Firefox.  You will have to take my word that this displays just fine everywhere else.
