A Mozilla Desktop Environment?
Andreas writes "A discussion at the mozilla.dev.planning list has given the birth to the idea of a Mozilla Desktop Environment. This sure sounds like a possibility for Mozilla as it already has many of the applications needed; and the company is thoroughly familiar with XUL, which is a more-than-potent language upon which to build a desktop environment. By building a desktop environment Mozilla wouldn't have to worry about drivers (and such) and could choose from a variety of kernels, and still be in the center of attention. Mozilla has to expand some of the applications for this to work, though, like adding local file management with Firefox."
Why don't they just pool their web browser, e-mail client and calender application into one big package. That would be a great start...

Think about the memory usage. Firefox struggles enough, think about running a full desktop environment. I won't until some of the memory usage comes down quite a bit.
XUL is already blamed for a lot of the speed issues with Firefox, why would I want the DE to be even slower? And why would Mozilla do this other than to try and get more attention? Do they have any ideas that are different enough from the existing environments (like KDE and GNOME or even enlightenment and XFCE) that they need to make a NEW environment?
In all honesty, unless Mozilla Corporation/Foundation has an actually INCREDIBLY AMAZING NEW idea that CANT be done with any of the existing DEs this is probably the stupidest ideas I've heard in a LONG time.
What are the goals? How will it be different? Or are they doing it just to do it?

Maybe we need to remind ourselves of the trials, tribulations, and pitfalls of both cruft (old junk) and feature creep (glitz and glam just for the sake of glitz and glam are neat--but they don't make for a good project path until it's stabilized).

The link which masquerades as being informative is to the submitter's website. It is no more informative and filled with just as much random conjecture as the summary here. And you get the thrill of seeing ads.
The Google Groups link is a dozen or so messages from a handful of people. It's a thread of "I like XUL and I think this could be a neat idea but there's no special work being done on this."
This is an article about something being possible, a something which has been thought of a hundred times before.
Breaking news!!
Ok, I'm no moz dev, though I loves me some Firefox, but didn't we learn not to mix our browser and desktop scripting languages before? What is there about this arrangement that would not be screaming for holes to be found and malware to creep across boundaries? It could be very cool, but it could really suck bigtime, too. Where do you want your file system to go today?

It depends on where the bloat is coming from. Potentially using common components/shared libs could reduce bloat relative to having mozilla browser + kde + gnome apps, each of which need their own bloat libs.
Engineering is the art of compromise.
10 Create web browser and email client.
20 Merge applications into single suite.
30 Steadily add programs and functionality to suite until it does everything badly.
40 Announce innovative new project to create simple, lean apps that break up bloated suite.
50 GOTO 10
How can I believe you when you tell me what I don't want to hear?
XUL is too slow to make an entire DE. Can you imagine a desktop environment WRITTEN IN JAVASCRIPT?!?!?! (or technically emca script?) My god, thats one freakishly scary (and slow, and memory intensive) desktop environment... I think it would make the people running XFCE and enlightenment scream, and the people running blackbox, rat poison, and other tiny WM head's explode.
And don't forget that on *nix XUL uses GTK's widgets... I can see the OOM Killer going wild already!
Don't get me wrong - I like the idea, and think it could work really well for the environments that will support Firefox across its (potentially unlimited) lifetime, but it seems to greatly overlap with javascript/flash. Each is practically limited to either specialist uses, or else work as least-common-denominator products for the potential Firefox environments. That means a lot of sprite games with simple interactions, graph and UI effects in popularized widgets, web portal software, and even the occasional spyware exploit finding a way to mark a user's trail. There will be ports of simple software from other environments, but limited interaction with the outside environment (by design), being chained to a time-limited browser session, and lack of the easy ability to really exploit the running environment will severely limit what toys and tools can really be created.
That's why I've taken a liking to Eclipse recently - it takes a nice set of the fast-development architecture of java development, and allows them to be used by C/C++, Python, and others cross-platform. Has anyone started working on a really nice integration of Eclipse into a Firefox plugin?

I've done a bit of stuff with XUL.
It's great if you want to do things like, say, a custom web browser or write your own iTunes -- The kind of thing that you'd usually write as a web-based app but you need local file storage and maybe access to online content that cross-site scripting preventative rules would prevent you from accessing in a regular browser.
If you need to do more than that, it's quite a chore. You have to start writing your own XPCOM components, which you'll have to compile on each target platform separately. There goes your easy cross platform compatibility.
The documentation for XUL and XPCOM isn't very helpful or well organized, and that's putting it nicely.
Language support is thin. C++ and Javascript are pretty much your only choices, although Python support is coming soon, apparently.
The question is, if you were going to develop a desktop environment from scratch, would you start by writing XUL? Would you then extend that by embedding JavaScript? I don't think so. Both Gnome and KDE tried the whole component thing with CORBA and abandoned it for performance and complexity reasons. Cross-platform is nice, but Java, GTK+, QT, and even C# provide better cross platform benefits with greater support and language compatibility than the XUL suite of tools.
Not only that, but I'd wager a Java desktop environment would be a better performer than one based on XULRunner. Not to mention, it would support more languages through Jython, JNI, etc.
It's a shame, because XULrunner could be a great platform. I hope they focus more on documentation and supporting other languages than redundant pie-in-the-sky projects like this one.

If you've got both Seamonkey and Konqueror installed on your system, browse the same set of sites with both. Make sure you disable caching for both, to prevent such caching from inflating each browser's memory usage. Also start from a raw X session, just to further eliminate any sources of inconsistency.
I just did that sort of a test on my Linux system, visiting a variety of sites (Slashdot, BBC, Tom's Hardware, FSF, Digg, etc.) with both Seamonkey 1.1.1 and Konquerur 3.5.5. I've also used Opera 9.01. Checking via top, I see that Seamonkey currently has a virtual memory image of 357 MB. Konqueror, on the other hand, is using a rather minimal 43 MB. Opera is just over Konqueror, at 45 MB. As this is the total size in virtual memory for each process, it also includes the overhead of any shared libraries.
So from those results, I think it's safe to say that there's a major problem with Seamonkey. Both Konqueror and Opera manage to keep their memory usage within reasonable bounds. As for the cause of Seamonkey's excessive memory usage, I can't say. It could be due to memory leaks. I'd guess it's partially due to their extreme overarchitecturing of their software. Regardless, it's a troublesome issue for them.
XUL seems like a decent enough idea to begin with, but in practice it's horrible. Anything more complex than your average browser extension, and it really starts showing its design weaknesses. It's buggy as hell too. That last point is particularly difficult to emphasise properly. It's buggy as hell. It seems like a natural step from the web to cross-platform desktop applications, but quite frankly, you are better off using your favourite scripting language and whatever bindings you can get to Qt/Gtk/whatever.
They keep pushing back XULRunner further and further - the first "stable developer preview" is a year old, there's no sign of the next version, and half the APIs available in the preview are obsolete. If it weren't for Firefox committing to it, everybody would have admitted it was dead already. Songbird? Democracy Player? Yeah, those projects are really zooming along development-wise *rolls eyes*. How about you build the simplest little MP3 player that actually works properly before thinking about anything as ambitious as a desktop environment.
I love the idea of XUL, I really do. But its only got one implementation, which totally sucks and is the kiss of death to almost everybody using it. I can't imagine the suckitude of an entire desktop environment built on top of it. I genuinely believe that if XULRunner doesn't get some gigantic improvements, it will eventually drag even Firefox down with it.
I thought the whole point of Firefox was to create a slimmed-down-yet-extensible browser that wouldn't suffer from the "kitchen sink" mentality that plagued the Netscape/Mozilla suite in the past. Sure, I guess it's possible to do a whole XUL based desktop environment . . . but why??
(and yeah, I know the same logic of Firefox --> d.e. bears similarities to the GIMP --> GNOME, it just seems odd to me to go through the massive effort required when there are so many simpler options to do mostly the same thing these days.)
I remember searching for such a Desktop Environment a year or two ago after experimenting with XUL, I ran across Symphony OS (http://www.symphonyos.com/) which uses the Mozilla platform for rendering and applications. It is called the "Mezzo Desktop Environment" (http://en.wikipedia.org/wiki/Mezzo_%28desktop_env ironment%29), and is available in Debian package format.
I remember testing a live-cd of symphony about a year ago and it seemed pretty intriguing. I really liked the desktop interface.
But anyway, from what wikipedia says, the Mezzo Desktop Environment is an incomplete platform (whatever that means), and if it is correct there appears to be work unfinished. However, anyone interested in contributing might want to take a peek under the hood and see if that project can be helpful and exactly what is "incomplete" about it.
"Progress comes from the intelligent use of experience."
This project http://www.symphonyos.com/cms/ seems to have something of the same ideas. Their GUI is simply based on FF.
SymphonyOS is a Linux distribution which uses a special desktop based in a browser.
Lets look at history so we don't repeat ourselves... Microsoft thought that embedding IE into windows (and when I say embedding I mean fusing together with no hope of separation) was a great idea but it turned into a disaster for security and to some extent usability. Now I do realize this is coming from a different angle, where a browser is going OS instead of an OS going browser, but in my mind, as far as security goes, local and non-local should be kept as separate as possible. Closely integrating the two is just asking for problems. You learn history so as not to repeat it.
Is this Mozilla's answer to Vista? Who ever can use the most ram and CPU power wins?

Let's look back in history. Dr Dos/Quarterdeck tried to create their own desktop environment, Desqview/X. Then Novell tried it with Dr Dos and WordPerfect. It didn't work because OS was not core to their business, and the desktop OS business is far more competitive than what they were used to. Overall this is a very bad idea. Mozilla makes middleware, not client OS components. If Mozilla does this, it may unfortunately be the iceberg that hit the Titanic.
I believe the project was called WebTop... it would have been a desktop environment that could run on top of any OS, and applications could be written for it using it's API... allowing the creation of totally portable applications and, if done right, making Windows essentially irrelevant. It was a revolutionary concept and was aimed right at the heart of Microsoft.
Unfortunately, Netscape was in the crosshairs of Microsoft already, and with the company losing money like crazy, WebTop never saw the light of day...
Until now!
Thanks,

We've been through this already. Remember Mozilla, and how it turned into bloatware, then had to be slimmed down for Firefox? Rmember how XUL was going to be a "platform" that would make Netscape into a Microsoft competitor?
Then there was XPCOM, the Mozilla answer to Active-X, Microsoft's bad idea.
We don't need another stupid "platform". If you want to run programs in the client, we have Javascript and Flash for the simple stuff, and Java for more complex tasks. Cross-browser compatibility, even.
Javascript + Nintendo DSi = DSiCade
Byzantine has been doing this for the last few years. Not bad to use. Surprisingly, even though it uses mozilla as a desktop it has much less memory usage than almost all other distros. And opening a browser is always instant on since it's already in memory. http://byzgl.sourceforge.net/old-index.html http://byzgl.sourceforge.net/wiki/index.php/Main_P age
Why not? I'll tell you why not ... if the desktop environment is anything like developing Firefox extensions, it'll be a piece of crap.
1. Why, oh why, when I install an extension, it merges XML configuration with several other files? Do you know how hard it is to manually take all that crap out if the uninstall works (which it often does)? And still leave Firefox stable? Didn't they learn ANY lessons from Windows Registry Hell?
2. To make this "your configuration is scattered and merged with other VERY IMPORTANT FILES" phenomenon worse, why are they linked with GUIDs? GUIDs?!?! So now, if I want to uninstall "Craptastic Extension 0.7", instead of searching for "Craptasic", I have to find out what its GUID first and then hunt down instances of the GUID. Thanks a lot.
3. RDF. Ugh. Wouldn't a domain-specific XML schema have been better. I find RDF too abstract, not human readable, and contrarian to many of the design goals XML was supposed to bring in the first dang place.
4. Inconsistency of layout structure across extensions. How is this possible? The too-open-endedness of RDF. When I first tried to learn how to develop a Firefox extension, I decompressed the archives of four of my favorite popular extensions. To my dismay, the severe differences in project layout structure from extension to extension didn't allow me to see any pattern. Because the RDF can make anything point to anything, the individual developers could just layout all the directories however they damned pleased. Constrast this a Java project organized by Ant and you'll want to scream.
5. Look at Eclipse, ffs! Now THAT is how you build extensible software! Consistent. Clean install. Clean uninstall. No Registry Hell. No &$^#ing GUIDs. No RDF as obfuscated as a bad Perl or Lisp program.
"Love heals scars love left." -- Henry Rollins
This was already done a few years ago, there was a company that did a complete desktop environment based on Mozilla. I was sold as a kind of appliance PC for the living room.
Here's an article on it (from 2002).
If I remember correctly that was where the original calendar code came from.
No no and thrice no.
The OS should have one and only job IMHO (or not so HO): Manage and control access to resources.
The desktop layer and even the command shell should in an ideal world be divorced from the underlying OS core layer. And taking this one stage further if a common OS interface API (something akin to POSIX) existed I should be able to take core-OS and put whatever GUI or CLI (yes CLI is still better for some tasks) I like ontop of the base layer.
The base layer can then concentrate on running the hardware, preventing rogue programmes from compromising the rest of the system etc - ideally:
core-os --> [sandbox 1] --> [desktop gui] --> [sandbox for each app]
With the user/admins being able to define very tightly which files can be shared between sandboxes. Programmes which interact heavily with other programmes could run in their own sandboxes...

I know this is Slashdot and all, but the article summary is grossly misleading. This is a public newsgroup. A random person, not affiliated with Mozilla, posted a message saying "hey, you guys should make Mozilla into an OS!!"
Mike Beltzner and Stuart Parmenter, who actually work for Mozilla, respond by saying "no, that idea actually sucks".
Somehow, this makes it onto Slashdot as "ZOMG Mozilla is making an os CONFIRMED!!!!!111oneeleventy!!11" Please stop spreading ridiculous, baseless claims.

I dunno. The protocol, far as I can tell is fine. The implementation, at least the standard X server, is a POS.
Meanwhile, some of the purpose-built X-servers do a good job. X-Glx with Beryl makes Aero look like ass. KDrive is light enough to fit on a floppy. X-Ming is a great tool for porting X apps to windows.
Also, your demands for an end to X-Windows based on a story about Mozilla Desktop Environment is kinda dumb; MDE would run atop XWin, just like any other DE.
