1827466 - Firefox 112 is not providing any information on about:support when dom.webgpu.enabled is set to true

Status: RESOLVED DUPLICATE of bug 1824638

(Core :: Graphics: WebGPU, defect)

Description

[Henrique Custódio]

Attachment: about:support

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/114.0

Steps to reproduce:

Firefox 112 is not providing any information on about:support. The problem happened in version 112 which is in Arch Linux testing repository and in Windows 11 version.
In version 114.0a1 of Firefox Nightly it is normal (Arch Linux). Version 114.0a1 of Firefox Nightly on Android is fine too.

Actual results:

Running through the terminal (Arch Linux), the following warning appears:

[ERROR glean_core] Error setting metrics feature config: Json(Error("EOF while parsing a value", line: 1, column: 0))

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Doesn't repro for me and we haven't received any other reports for this. Changing to Toolkit-General as the component as that is a better match and will potentially get the right attention to ask for additional information to debug further.

Hello,

I could not reproduce the issue on the latest Release (112.0.1/20230414125621) or Nightly (114.0a1/20230417092144) under Windows 10 x64 and Ubuntu 16.04 LTS.

The about:support page displays the expected information with both the default theme and the dark theme applied.

Currently I don’t have access to Win 11, but once I have I will try and see if the issue occurs there and update the report.

I managed to test the latest Release 112.0.1 on Windows 11, but could not reproduce the issue. The about:support page is fully displayed on both default and dark theme.

[Thomas Ludwig]

I can confirm the same problem and the same warning appearing in the terminal for Firefox 112 on Arch Linux.

Comment 6

[Thomas Ludwig]

Additional warnings:

console.warn: "Skipping Glean as no metrics id is passed"
JavaScript error: resource://gre/modules/AddonManager.jsm, line 2909: NS_ERROR_NOT_INITIALIZED: AddonManager is not initialized

Hi there, are you able to also reproduce this in Firefox 112 downloaded from mozilla.org?

It'd also be useful to check what errors appear in the browser console (opened with ctrl-shift-j) - and expanding any exceptions/errors to copy their stacks.

Comment 9

[Thomas Ludwig]

I'm happy to report that for me everything is okay again. I noticed that the problem didn't occur in a new profile and remembered that I had recently set dom.webgpu.enabled and gfx.webgpu.ignore-blocklist to true. After reverting those changes about:support works as it should. Sorry for the noise. So the reporter's problem might also be caused by changes in about:config.

Yes, on Windows 11 this problem occurred with the version downloaded from the Mozilla website. On Arch Linux it was with the repository version and with the one available on Flathub.

[Henrique Custódio]

Following Thomas Ludwig's instructions, disabling the dom.webgpu.enabled parameter, the problem disappears. I had not changed the gfx.webgpu.ignore-blocklist option to true. The information reappears on the about:support page. I was able to reproduce this behavior on Windows 11, Arch Linux (repository and Flathub version). I haven't had any problems with the Nightly version I use on Arch Linux. This version I downloaded from the Mozilla website.

Thanks. I think the relevant bit is:

Jim, is this effectively fixed by bug 1824638?

Comment 15

[Erich Gubler [:ErichDonGubler]]

:Gijs: I believe so, yes. See the screenshot I posted at https://bugzilla.mozilla.org/show_bug.cgi?id=1822168#c3 proving that we currently are getting WebGPU adapter information now.
