I could reproduce on a Pixel 4 emulator with Android 13. Doesn't reproduce on a Pixel 4 emulator with Android 16.

Carmen, since this is device dependent and I was only able to test on an emulator, would you mind verifying the fix on a build installed via TryFox from this try?

EDIT: Unfortunately steps to enable nova onboarding don't work on this build. We agreed to wait to verify the fix on nightly.

Looking at the latest Nightly 149, I can confirm the issue is no longer reproducible and the pagination dots are no longer overlapped by the device’s buttons.
However, the dots are now located very close to the Onboarding cards.
@Marcin, can you please confirm that this is the expected UI for the pagination dots?

The screenshots don't show the expected UI. The background should be visible under the navigation buttons and the dots should be closer to the bottom. Let me try a different fix.

Comment 15

[Marcin Koziński]

We removed edge-to-edge support in bug 2020423, which makes this issue obsolete. If we enable edge-to-edge again, then it's important to test for this scenario again, but for now I'm closing this report.

This issue occurs again in Firefox for Android 150 (2026-03-18) after re-enabling the Edge-to-Edge feature. It was tested on Google Pixel Pro (Android 16) and Samsung S24 Ultra (Android 16).
