For QA: please test in the latest Nightly that there are no issues related to nav bar and status bar on Android 15/Android 16 devices.
Please also test scenarios in https://bugzilla.mozilla.org/show_bug.cgi?id=1933488.
Thank you!

There were no unknown/new issues found during testing the nav bar's and status bar's functionality and UI, there was an early unusual beahvior of the long press of the system back button which sometimes did nothing, other times moved the app to the background, but those tests were done with an earlier version and compared to Chrome on which the behavior was similar.
On the latest Nightly the behavior was the usual "displaying the recent tab history".
I couldn't reproduce any of the scenarios presented on this ticket: https://bugzilla.mozilla.org/show_bug.cgi?id=1933488.

Devices used:

• Google Pixel 9 Pro XL (Android 15);
• Google Pixel 7 (Android 16 Beta);

Build tested: Firefox Nightly 137.0a1 from 2025-02-26.
