[Phil Ringnalda (:philor)]

Related to, but *not* a duplicate of, bug 220253 - we could avoid the 404 without being sensible enough to have a real about:about.

Comment 3

[Markus Multrus]

This still affects FF3 Beta4. Will there be a fix for this at the final release? No real showstopper, but ugly though...

Comment 4

[Mike Beltzner [:beltzner, not reading bugmail]]

Not gonna block the final release, no.

Comment 6

[Mike]

Yeah, I noticed that too, was going to come and submit it, but you beat me to it.

Its not horrible, but still ugly... 

Comment 9

[Reed Loden [:reed]]

glandium, can you re-attach your patch here and request review? Thanks!

Comment 10

[Mike Hommey [:glandium]]

Actually, I'm wondering... since everyone except firefox wants it, why not have it in toolkit and let firefox unregister it ?

Comment 11

[Phil Ringnalda (:philor)]

We could call that approach "the bug 365852 solution," if not for the fact that it's already wontfixed.

Attachment: patch removing about:about

Okay, so this is the patch I originally sent to #434842, with an additionnal hunk to make it more complete.

(Bug still there)

Comment 19

[Boris Zbarsky [:bzbarsky]]

I'm not sure I see why this patch makes sense.  Is firefox the only thing setting MOZ_XUL_APP?  Would it make more sense to remove about:about from here altogether and let apps that do want it register it?  That was suggested in bug 365852 too, no?

In any case, I'm clearly not qualified to review this, since I don't know what he MOZ_XUL_APP define actually means.

Actually, it seems that most applications except firefox want it... I know firefox is the big boy, but i don't think that grants bothering all other applications.

MOZ_XUL_APP should be defined for any application using toolkit.

Comment 21

[Mike Hommey [:glandium]]

Personally, I would just move the aboutAbout.html file in toolkit and have it installed. If firefox maintainers really don't like this page, they can unregister it from somewhere in browser/

Comment 22

[Boris Zbarsky [:bzbarsky]]

> MOZ_XUL_APP should be defined for any application using toolkit.

In which case this patch would disable about:about for all toolkit-using apps, no?  That doesn't seem to match the first part of comment 20 well....

I would be fine with adding aboutAbout to toolkit.  But I'm not a toolkit peer.

patch removing about:about

I can't even set review- on that request (or review+, for that matter)...

Comment 25

[Mike Connor [:mconnor]]

nice to have, not a big deal either way.

Comment 26

[Hello]

still not fixed

Comment 30

[Reed Loden [:reed]]

Attachment: patch - v1

As per bug 451909, all apps set MOZ_XUL_APP now, so let's just kill this unused code.

Comment 31

[Boris Zbarsky [:bzbarsky]]

Reed, I'm not sure I follow.  Doesn't this just remove about:about?

Comment 32

[Reed Loden [:reed]]

(In reply to comment #31)
> Reed, I'm not sure I follow.  Doesn't this just remove about:about?

Yes, I thought everybody had gotten rid of their implementations for this (meaning we could just remove it), but apparently SeaMonkey still has it... should I just #ifdef it only for SeaMonkey instead?

Comment 33

[Boris Zbarsky [:bzbarsky]]

I don't think we want an #ifdef here.  We should't need an ifdef to do what comment 19 suggests.

Also, see comment 20 about non-Firefox about:about impls...

Comment 34

[Phil Ringnalda (:philor)]

I sort of thought the point of http://mxr.mozilla.org/comm-central/source/suite/browser/nsAboutAbout.js was that SeaMonkey didn't trust Firefox not to do exactly this, and so they implemented it themselves, and now removing the docshell redirect is only going to screw over Camino, and only if they move to mozilla-central rather than going to WebKit.

Comment 35

[Boris Zbarsky [:bzbarsky]]

Yeah, if the patch doesn't break seamonkey, and if xulrunner apps (which is what I assume Mike Hommey was talking about) don't care, then it's fine.

What XULRunner apps (besides SeaMonkey) implement about:about? I don't know of any... so, I think we're fine.

patch - v1

OK, let's do this, then.  Please check whether this makes aboutAbout.xhtml unused, and remove it if so (that is, if Seamonkey has forked it).

Please keep an eye out for breakage.

Trying to browse to about:about leaves the content area blank, with the following messages in the Error Console:

The latter one happens twice.

Now I'm going to test a recent tinderbox-build (maybe this nightly didn't include the fix).

Nope, no change. Should I REOPEN or file a specific bug for SeaMonkey?

Sounds like a SeaMonkey-only bug to me, so file a new bug for SeaMonkey.

Filed bug 461552.

Comment 45

Re comment 44: possibly the dupe wasn't really a dupe, but a regression?

Using Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.2a1pre) Gecko/20090404 Minefield/3.6a1pre, i'm getting a "The URL is not valid and cannot be loaded". Can anyone please check if this still works or if this has regressed?

Comment 46

[Phil Ringnalda (:philor)]

That is precisely what you should get: the fix was to make about:about just like about:foopygoats, because neither one is supported in Firefox. Bug 469896 was filed about 3.0.x, where this wasn't and won't be fixed, so there it gives a file not found error instead of a proper (for an about: URL that isn't supported) "not valid and cannot be loaded" error.

[John Vivirito]

I can confirm on 3.5
