Status: VERIFIED FIXED

(Core :: Widget: Cocoa, defect, P3)

Description

[Michal K]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:70.0) Gecko/20100101 Firefox/70.0

Steps to reproduce:

1. Open clear Nightly's profile
2. Enable "Title Bar" via "Customize..."
3. Go to about:config and set configuration "full-screen-api.macos-native-full-screen" to "true"
4. Go to Fullscreen
5. Title Bar is still visible despite of it should be gone like it is if full-screen-api.macos-native-full-screen is false

Actual results:

If full-screen-api.macos-native-full-screen=true then Title Bar is still visible in full screen mode despite of it should be gone. If full-screen-api.macos-native-full-screen=false, then Title Bar is gone in full screen mode

Expected results:

Title Bar should be gone, should disappear in both cases:

• full-screen-api.macos-native-full-screen=false
• full-screen-api.macos-native-full-screen=true

Hi Michal,

I was able to reproduce the behavior reported using the latest version of Firefox Nightly 70.0a1 (2019-07-30) (64-bit) for Mac OSX 10.14 but only for this case:

1. Go go about:config
2. Choose full-screen-api.macos-native-full-screen=true
3. Open a video in full screen

Actual result: title bar is visible in full screen.

When I select full-screen-api.macos-native-full-screen=false and open a video in full screen mode, title bar is not visible. Is this the expected result?

Can you please confirm if you see this behavior too in the latest Nightly? You can download it from here: https://nightly.mozilla.org/

Thank you for your report.

Hello Virginia,

I updated to the latest Nightly 70.0a1 (2019-07-30) (64-bit) and I confirm, that this faulty behaviour is still reproducible. And yes, this "faulty" behaviour is reproducible with configuration full-screen-api.macos-native-full-screen=true only.

Behaviour of full-screen-api.macos-native-full-screen=false (default setup) is correct from my perspective, because it was always like that.

I also think, that this bug is related to this bug 1403085, which led me to change configuration to true and check how it works.

If you have some further questions, please let me know.

Hi Michal,

Thanks for your feedback! I also think it may be related to the bug you mentioned.
I'll add a product and component so the devs can take a look at it.

Reproduced the issue using Firefox 88.0a1 (20210301093612) on macOS M1 mini 11.2.2 and macOS 10.15 following comment 0 steps.

I can no longer reproduce the issue with Firefox 88.0a1 (20210303215027) on macOS M1 mini 11.2.2 and macOS 10.15. The Title bar is no longer displayed when opening a video in fullscreen or entering fullscreen with Firefox. I think this is fixed by 1633119.
