1915714 - Hide the toolbar while the page is still loading

Status: NEW

(Firefox for Android :: Toolbar, enhancement, P3)

Description

[Aarjav [:aarjav]]

Attachment: Toolbar doesn't while the page is still loading

Steps to reproduce

1. Open any website that takes time to load.
2. On opening, the loading bar appears while loading the webpage.

Expected behavior

• Make the toolbar hide when the user scrolls while still displaying the URL and the loading bar.
• This might help users think of the perceived performance of the browser as being faster.
• Also after this has been applied, the scroll to hide behaviour of the toolbar while the page is loading and after it has loaded will be the same.

Actual behavior

• The toolbar sticks and stays displayed until the loading bar finishes loading and then hides when the user scrolls.

Device information

• Firefox version:
• Android device model:
• Android OS version:

Any additional information?

The experience/ui needs to be designed.

Not hiding the toolbar while the page is loading is a conscious decision to prevent scenarios in which the dynamic toolbar is hidden and then cannot be shown back again when the page fully loads.
This scenario could be improved by bug 1914119.

Is this bug a duplicate of bug 1910268?

• Firefox displays the address bar before loading the second page. This causes the first page to shift.
• Chrome displays the address bar after loading the second page. This causes the second page to shift.

Was meaning to search the original issue which needed this functionality.
Great that we still have the history in Github, found it here - https://github.com/mozilla-mobile/fenix/issues/18034 with a video also for what can happen if we allow scrolling while the page loads - while the layout is not fully loaded and we don't have a guarantee on whether the the toolbar should be scrolled or not - even with a dynamic toolbar swiping on certain elements should not translate it.
