Tapping the top edge of the screen in landscape orientation does not scroll to the top of the page

[cpeterso]

Steps to reproduce

1. Load a long web page, such as https://en.m.wikipedia.org/wiki/Main_Page
2. Hold the phone in portrait orientation.
3. Scroll down the web page.
4. Tap near the top edge of the display.
5. The toolbar will appear.
6. Tap near the top edge of the display again.
7. The page will scroll back to the top of the page, as expected.
8. Now rotate the phone to landscape orientation.
9. Repeat steps 3-6 above.

Expected behavior

The page should scroll back to the top of the page, like it does in portrait orientation.

Safari scrolls to the top in landscape orientation, as expected.

Actual behavior

Nothing happens. The page does not scroll to the top of the page in landscape orientation in Firefox.

Chrome iOS doesn’t scroll to the top of the page in landscape orientation either, but Safari does. Maybe this is a bug or limitation in the WebView used by Firefox and Chrome?

Changing Firefox’s toolbar position from top to bottom has no effect on this bug.

Device & build information

• Device: iPhone 12 running iOS 16.2
• Build version: I can reproduce the bug in the Firefox iOS version available in Testflight: 107, 108, and 109. I can also reproduce in Firefox Focus 108.1.

This seems to be normal iOS pattern. You need the status bar (where the time shows) in order to trigger the scroll. Other native iOS apps, like Messages, also does not have this behaviour. I am going to change this to a feature request.

Note that Safari implements this (non-standard?) behavior in landscape orientation without the status bar.

This feature request is still valid. Safari solves this issue by showing the toolbar at the top in landscape orientation, even if the toolbar is on the bottom in portrait mode.

Chrome also shows the toolbar on the top in landscape orientation, but tapping the landscape toolbar didn’t scroll to the top of the page.

I retested Safari on iOS 17.4.1 and it no longer scrolls to the top of the page in landscape orientation. So Firefox now matches both Safari's and Chrome's behavior in landscape orientation.

So this issue is no longer a feature parity bug and is now a feature request to scroll to the top of the page in landscape orientation. 😁
