950986 - "Windows 8 Touch" (switch to Metro) not appearing in Australis menu panel or customization UI on a Windows 8 tablet

Status: VERIFIED FIXED

(Firefox :: Toolbars and Customization, defect, P2)

Description

[Matt Brubeck (:mbrubeck)]

The "Relaunch in Windows 8 Touch" button is supposed to appear in the menu panel when Firefox is running on Windows 8 or higher, but KarstenS on SUMO reports that it is not included anywhere, running Nightly on a Dell Venue Pro 8 with Windows 8.1, even after setting Nightly as the default browser and using the "Restore Defaults" button in the customization panel:

We haven't seen this in our own testing, and I don't know what might cause it.  If anyone can figure out steps to reproduce this, that would be great.

Technical details from that tablet: http://i.dell.com/sites/doccontent/corporate/secure/en/Documents/dell-venue-8pro-brochure.pdf

Additional information: With firefox builds from Aurora branch it is working as intended to launch in Metro mode. The issue happans in the nightly branch.

If you open the browser console (ctrl+shift+j on the desktop version) and evaluate:

Services.sysinfo.getProperty("hasWindowsTouchInterface")

What is the returned value?

Comment 3

[KarstenS]

Device: DVP8, Branch: nightly, Metro working: no, Result of that command: false

Device: DVP8, Branch: nightly, Metro working: YES, Result of that command: false

Device: Desktop PC (without any touch device), Branch: nightly, Metro working: YES, Result of that command: false

Maybe the detection of the touch device is not working as it should, because the DVP8 has got 2 digitizers? One for fingers and one for pen.

When you look at the first and the third test, there is the question: does this value really belongs to that issue?

Corrected line:

Device: DVP8, Branch: AURORA, Metro working: YES, Result of that command: false

Switching from Metro to desktop was possible in this case. Switching back to metro not, because of the missung entry in the menu.

That's really weird, since hasWindowsTouchInterface should be set to "true" on any computer running Windows 8.0 or later, and the "Relaunch in Metro" menu item shouldn't be shown unless that property is true.

Comment 8

[Matt Brubeck (:mbrubeck)]

If you are seeing this problem, what do you get if you run the following code in the Browser Console (control-shift-J) in a version of desktop Firefox where the problem occurs?

Services.sysinfo.getProperty('version')

Comment 9

[Matt Brubeck (:mbrubeck)]

Another question:  Is your Firefox/Nightly/Aurora application configured to run in "Compatibility mode"?  http://support.microsoft.com/kb/292533

Comment 10

[Stefan Seidel]

Same problem here.
Services.sysinfo.getProperty("hasWindowsTouchInterface") = false
Services.sysinfo.getProperty('version') = 6.3
No compatibility mode.
But: using amd64 build.

Comment 11

[Matt Brubeck (:mbrubeck)]

Maybe the Windows 64-bit nightly does not have Metro enabled for some reason.  Could you paste the contents of the "about:buildconfig" page into this bug, please?

Does the same problem occur in the 32-bit nightly build from http://nightly.mozilla.org/?

no

Comment 15

[Marina Samuel [:emtwo]]

If we can confirm that the metro button in the file menu in Aurora is working but not the Australis one on Nightly, and if we still can't identify why XP_WIN or MOZ_METRO is not defined, we can remove those checks and instead check for sysInfo.getProperty("name") which is what is currently being done on Aurora.

I have the same issue with my Surface Pro from Microsoft with Windows 8.1 : the button doesn't appear.
I'm using Nightly 29.0a.1 win32 without any compatibility mode.

I hope knowing that the problem occurs also on 32-bits builds will help. I'm available for any other test. Just mail me.

[ChrisF]

I just registered to Bugzilla due to this bug.
Same problem here, no modern UI even though it has all the standards, no such button.
Unable to confirm if it works on Aurora: Should there be a button (I wouldn't know where) or should it just work after assigning the standards? The latter didn't work.

Device:
Lenovo IdeaPad Yoga 13 (ultrabook that can be used as tablet)
Windows 8.1

Services.sysinfo.getProperty('version') 6.3
Services.sysinfo.getProperty("hasWindowsTouchInterface") false

Hi Chris, Thanks for reporting. Are you able to switch to the modern UI on Aurora? There should be a button under the file menu that says "Relaunch in Windows 8 Style Aurora"

Yes I can switch to modern UI on Aurora 28.0a2.
And for the record, I used Modern UI on Nightly 28 (before the introduction of Australis menu panel). Since the 29th version, I'm not able to do it anymore.

Yes, after installing Aurora 28.0a2 and deinstalling Nightly (which kept the standards no matter what) I was able to switch to Modern UI in Aurora using the button under the file menu.

Hope that helps.

Comment 22

[Marina Samuel [:emtwo]]

Hi Brian,

We seem to be having an issue where sysinfo.getProperty("hasWindowsTouchInterface") returns false despite sysinfo.getProperty('version') >= 6.2

Which seems to imply that either XP_WIN or MOZ_METRO are not defined on some win8 builds so users cannot see the 'switch to metro' button. However the button shows up on Aurora which doesn't use these flags.

Do you have any idea why this may the case? If not, does it seem reasonable to remove XP_WIN and MOZ_METRO checks from http://dxr.mozilla.org/mozilla-central/source/browser/components/customizableui/src/CustomizableWidgets.jsm#780 and http://dxr.mozilla.org/mozilla-central/source/xpcom/base/nsSystemInfo.cpp#179

and instead check for os name == "Windows_NT like we do on Aurora?

Thanks!

Comment 23

[Matt Brubeck (:mbrubeck)]

I think the problem is the atof() call here, which will fail in locales where the decimal separator is not a period:

It's impossible unless the users are using self-made builds because XP_WIN and MOZ_METRO are build-time options.

[Approval Request Comment]
Bug caused by (feature/regressing bug #): 945842

User impact if declined: Users with locales using ',' instead of '.' as a separator would not see the button in Australis to switch to Metro

Testing completed (on m-c, etc.): Tested locally and two users with the issue have tested a try build included in this bug

Risk to taking this patch (and alternatives if risky): Low risk, only metro-related code uses the "hasWindowsTouchInterface" sysinfo property

String or IDL/UUID changes made by this patch: none

This (neither the "fixed" version linked here nor nightly nor aurora) did unfortunately not fix the problem for me on an iconia w511 running win8.1,
Services.sysinfo.getProperty("hasWindowsTouchInterface") true
Services.sysinfo.getProperty('version') "6.3"
Services.sysinfo.getProperty("name") "Windows_NT"

Do you not see the button when opening the customization UI in Nightly? (right click the toolbar, "Customize...")

If not, please file a new issue: https://bugzilla.mozilla.org/enter_bug.cgi?product=Firefox&component=Toolbars%20and%20Customization and either CC me or link to it here. Thank you!
