1825730 - [UX] Improve the UX of saving pdf's in the build-in pdf viewer

Status: UNCONFIRMED

(GeckoView :: PDF Viewer, enhancement)

Description

[f.ostkamp]

Steps to reproduce:

Recently the behaviour of opening pdfs in the browser changed. In the past, download links for pdf's were opening a popup about saving the pdf.
Now this changed to opening the pdf in the browser.

I wanted to save the pdf though and consequently searched for some way to download this pdf to my device.

Actual results:

Initially I wanted to file a bug for not being able to save the pdf that is opened.
I searched for a "Save pdf..." button in the three-dot context menu, but didn't find anything. Than I long tapped on the pdf to see if some kind of menu could be opened that would provide access to that function.

I then found out that this option is hidden in the sharing menu (from this bug https://bugzilla.mozilla.org/show_bug.cgi?id=1812124). I would never have looked there, because I would only open the sharing menu in the expectation to send the link or the file to someone else. I wouldn't consider downloading a file to my device sharing it with something.

Expected results:

I would have expected either an entry to save the file either in the three-dot context menu, or in a context menu that is accessible by long tapping somewhere in the pdf.
