[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Firefox::PDF Viewer' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

It's likely a file handling issue rather than a pdf.js one: pdf.js renders the pdf but doesn't "choose" the window/tab where to render it.

In BrowserContentHandler I see
handURIToExistingBrowser (resource:///modules/BrowserContentHandler.jsm#941)
dch_handle (resource:///modules/BrowserContentHandler.jsm#1188)
with urilist.length == 1

See https://bugzilla.mozilla.org/show_bug.cgi?id=1792466#c9, the problem is that Firefox in invoked by Windows multiple times, one per each file selected, and because of that we don't know which window was used for the first pdf or for the whole operation, it's totally separate operations from our point of view.

This is a lower priority than bug 1792466, since apart from the annoyance it's not a huge problem that pdfs are opened in different windows.
