There is additionally no "Open in app" option in "three dots" menu.

What is your default pdf viewer set to? https://updf.com/mobile-app/change-default-pdf-viewer-android

My default PDF viewer is set to Adobe Acrobat. I have confirmed this by opening my device's file manager app and opening a PDF; I am not asked what app I wish to open the file in. It opens in Adobe Acrobat.

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

I will confirm this ticket, since I was able to reproduce this issue.
I have PDF reader as the default PDF viewer. However, every time I tap on "Open" after downloading a PDF, the file opens in Firefox for Android.
Tested on the Fenix Nightly 1360.0a1 from 1/14, Beta 135.0b4, and 134.0.1 release build, with a Google Pixel 6 (Android 15), and a Vivo v23 (Android 14).

Hi,
Thanks for reporting this issue. I'm going to mark this as resolved because this was reverted over in Bug 1941609 in versions 135 and later. You should be seeing the old behaviour when 135 goes to release on February 4, 2025. We are re-evaluating the default PDF behaviour that we want in fenix
