### Steps to reproduce 1. Tap the address bar. 2. Tap the QR-code-scanner button at the right side of address bar. ### Expected behaviorI only see a few `android-reviewers` pushes in there. QR code scanner opens. ### Actual behavior Black screen, "No camera available on device" ### Device information * Firefox version: Nightly 135.0a1 2024-12-19 * Android device model: Pixel 6a, Pixel 8 * Android OS version: Android 15 ### Any additional information? This is a recent regression. With mozregression, I determined Nightly 2024-12-17 is "last good" and Nightly "2024-12-18" is "first bad". Using the hg revisions from "About Firefox" UI in those builds, I got this regression range: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=10fe3e4fee81&tochange=af703e4a9001 Not sure what in there might be most-related; royang, maybe you have some ideas? [Tracking Requested - why for this release]: pretty substantial functional regression; can't scan QR codes in Firefox anymore.
