wrapping up the Newmoon Browser package

wrapping up the Newmoon Browser package

[ng0]

Hi!

I need some final input on topics I'm more liberal about.
Many many moons ago I started the work on Pale Moon. This
package has now moved into New Moon, which is what we are
allowed to redistribute with modifications (Pale Moon without
branding).

Issue 1 I addressed so far: The default homepage (after first
start and in general default) called a website which is questionable
in my opion: https://palemoon.start.me

I have patched the default home page to be gnu.org and gnu.org/s/guix


Next, can I keep the default bookmarks? They are:
- https://www.palemoon.org
- http://forum.palemoon.org/index.php
- https://www.palemoon.org/faq.shtml
- https://www.palemoon.org/releasenotes.shtml



Finally, about:addons let's you install Addons from 2 repositories:
Pale Moon Add-ons Site and Mozilla Add-ons Site.
"Search all add-ons" queries the 2 repositories and lets you install
add-ons from the repositories.

In an ideal world, I would have figured out the integration for
plugins in the gnu-store by now. But I'm still testing, so:

How do I treat the addons page and functionality?

Can the home page be customized in Newmoon?  If so, then in my personal
opinion it would be good to leave the upstream default as-is, and let
the user decide whether to change it.  The page seems fairly benign to
me, but I understand that some people might object to some of the links
(e.g., to Facebook).

As far as the FSDG is concerned, I don't think this matters either way.

These all seem benign to me; presumably they will be useful for a user
of a browser based on Pale Moon, right?  Again, I feel like respecting
upstream's decision on the defaults is the right way to go.

Do these add-on repositories contain or encourage the use of non-free
software?  If so, to remain FSDG-compliant, it might be necessary to
change Newmoon so that it points somewhere else, such as the Free
Software Directory (this is what GNU Icecat does when you click on "Get
Add-ons").

On the technical side of things, is it possible to install plugins in
the browser, or does it fail with Guix-specific problems (e.g., tried to
modify a file in the immutable store)?  If it's possible to install
plugins in "the usual way" (whatever that is for Newmoon), then that's
great, and maybe someday we can figure out how to integrate those
plugins with Guix, too.  If it isn't possible to install plugins, then
that's not so great, but if the browser is usable in spite of that, then
it's probably better to add the browser now and iterate on it - we could
figure out how to accommodate the plugins later.

Yes, I think you can create a profile and log in to customize.

Huh. So this page would be okay in FSDG? Interesting.
I object to its content, but changes are trivial to make.

It's the original Mozilla Webstore. I have no issues with that, but as far
as Icecat existence goes, GNU seems to have a problem with it.
The Pale Moon / Moonchild Productions webstore is more restricted in
licenses as far as I remember.

I'll give it a try and report back.

I've started experimenting with the extensions integration with Firefox ESR 54+,
if that is what you mean. As Gentoo patches it to make use of a vendor location
for other Mozilla-based products, and Archlinux as well as Nix, my guess is
that you just have to figure out the right combination of punchholes for our
Lispmachine :)
If that is what you meant.

http://addons.palemoon.org/extensions/ works manual. content from the few samples
I looked at point out licenses, only OSI-approved I found.
If you submit an addon: http://developer.palemoon.org/Add-ons:Site/Submit
you get to go through the submission and acceptance process, which includes:
- Optionally, you could also provide the following, to be shown on the add-on listing:
  - License - both OSI-approved licenses and custom licenses are allowed here. If a license is not provided, a default copyright notice is shown instead.

The current webstore of Mozilla is, unless you know how to navigate to old versions,
useless because in New Moon it displays this for Ghostery:

"This add-on requires a newer version of Firefox (at least version 52.0). You are using Firefox 27.9."

Is this good enough for us to mark Mozilla webstore as unusable for those
who don't want to hack around it ;)?

I'vre installed Ublock updater, worked. I installed another addon, same.
So I guess despite my very small sample we could say in general addons
are functional.

Since it may provide non-free software, we should not display the
default palemoon add-on interface.

No.  The same applies as above.  (It doesn’t really matter that in the
end installing the software doesn’t work, in my opinion.)

Okay, thanks for the further insight. I'll continue hacking Newmoon and see
what I can come up with.

I intended that statement as my own personal opinion, not as any sort of
official determination.  Let's discuss this and make sure we choose the
right approach.

To that end, I'm curious: can you share more about why you believe that
we should change the home page?  Because we follow the FSDG, we
definitely should do something like that if including the default home
page without changes would in fact cause us to violate the FSDG.  That
said, even if leaving the default home page in would not cause us to
violate the FSDG, we may still choose to change it if there is a good
reason to do so.  For example, hypothetically, if the web page's default
home page contained malware, then surely that would be a problem.

> Thanks for taking a look at this :)

My pleasure!  Thank you for taking the time to work on it.

Do you know if the New Moon browser supports EME?  If so, it would need
to be disabled somehow.  The GNU FSDG specifically prohibits browsers
that support EME.

I suspect that the default home page and bookmarks will need to be
changed.  Otherwise, we would be steering users towards obtaining the
Pale Moon browser, whose binary distribution is restricted by a nonfree
license.  See <https://www.palemoon.org/redist.shtml>

We definitely need to avoid steering users toward the Mozilla Add-ons
Site, or any other add-on site that is not committed to including only
free software.  We could instead steer users toward the list of free
add-ons that's used by GNU IceCat.

Thanks for working on it.

I have no idea if it has support for EME. I will check next month.

Have you read my follow-up Emails with more details? I'm curious if
due to the issues mentioned there this is still necessary from the
GNU view on things.
I have no strong opinion on keeping the addons.

Actually I was able to find it now:

Media support
Media support is a regularly-discussed topic for Pale Moon users, since part of the user base would prefer a browser to also be a full-featured and fully dedicated&specialized media player. This is, however, not a goal of Pale Moon because of the inherent shift of focus from document content to media content. That being said, the Web has shifted to be more visual-media heavy and as such will require a browser to at least to some extent take on the media player role.

The following specific media streaming feature(s) is/are not on Pale Moon's roadmap:

    In-browser DRM (EME)

We are extending the browser (especially for Linux) with FFmpeg media as a replacement for the (generally problematic) GStreamer and libstagefright solutions that are currently in place. Work is underway to make this the default decoding/media back-end for all supported platforms.

Looks good.  While this roadmap was last updated July 2017, I think we
can assume for now that EME is not currently an issue for the New Moon
browser.  Thanks for checking.

I skimmed your other emails in this thread, but I'm not sure what
details you're referring to.  However, the GNU FSDG requirement is that
we may only steer users to third-party add-ons repositories that are
committed to including only free software.  Can you find evidence that
Pale Moon has made such a commitment for their add-ons repository?

    Thanks,
      Mark

Hi

I did not find any such statements. I did find non-free addons though. 
E.g. FireShot listed here: 
https://addons.palemoon.org/extensions/tools-and-utilities/

It took some time to find a non-free one, so I guess they are rare like 
1% of the total or less.

Thanks for looking into it.  The Guix project is committed to following
the GNU Free System Distribution Guidelines (GNU FSDG).  This includes a
commitment to not refer to third-party repositories except those
committed to including only free software.  Therefore, given your
findings, a prerequisite to including Pale Moon/Newmoon in Guix would be
to modify it so that it does not steer users toward addons.palemoon.org,
and never suggests installing nonfree plugins, etc.

The GNU FSDG states:

    A free system distribution must not steer users towards obtaining
    any nonfree information for practical use, or encourage them to do
    so.  The system should have no repositories for nonfree software and
    no specific recipes for installation of particular nonfree programs.
    Nor should the distribution refer to third-party repositories that
    are not committed to only including free software; even if they only
    have free software today, that may not be true tomorrow.  Programs
    in the system should not suggest installing nonfree plugins,
    documentation, and so on.

    For instance, a free system distribution must not contain browsers
    that implement EME, the browser functionality designed to load DRM
    modules.
