229737 - [RFE] Favicons for XUL error pages

Status: RESOLVED FIXED

(Core :: DOM: Navigation, enhancement, P3)

Description

[Minh Nguyễn]

User-Agent:       Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.5) Gecko/20031007 Firebird/0.7

The XUL error pages that are still under construction should have favicons, to
make it easier to tell when an error has occurred in one of the open tabs.

Reproducible: Always

Steps to Reproduce:
1. Enable XUL error pages. (Set "browser.xul.error_pages.enabled" to "true")
2. Go to a website that'll time out, or to one that doesn't exist. (I provided a
URL above if you're out of ideas.)
3. Open a bunch of other tabs and do some regular browsing.

Actual Results:  
Once the original tab loads the XUL error page, the tab displays the normal page
proxy icon (which usually looks like a sheet of paper or a bookmark).

Expected Results:  
In order for the user to more quickly realize that there is a problem, the tab
with the XUL error page should have a special favicon (for example, a red circle
with a white "x" on it). The image itself should be part of the theme.

This would probably involve adding the following after the <style> tag:

<html:link rel="icon" href="chrome://global/skin/icons/luna-error-small.png"
type="image/png" />

or:

<html:link rel="icon" href="chrome://global/skin/icons/neterror.png"
type="image/png" />

And adding an appropriate image to the default theme.

[Minh Nguyễn]

Whoops. Ignore the first line of code I gave.

Comment 2

[Chris Neale]

doesn't need to be as complicated as that

if you have the scriptstatus extension for example, you could use this in

docshell/resources/content/netError.xhtml

  <link href="chrome://scriptstatus/content/error.png" rel="icon" type="image/png"/>

obviously this would want something global, and guaranteed to be in any given theme

Comment 3

[Jeff Walden [:Waldo]]

Confirming.  Sounds like a good idea to me!

Comment 4

[Robert Parenton]

-> All/All

Comment 5

[Ross Shannon]

This would be extra cool when bug 28586 is fixed. Maybe the standard document
favicon with an x, similar to IE's broken images?

Comment 6

[Chris Thomas (CTho) [formerly [e-mail] [e-mail]]]

->me
->core (this lives in docshell)

See the URL for two possible icons (thanks to Wolf for the icons).  Which one
should we use?

Comment 7

[Chris Thomas (CTho) [formerly [e-mail] [e-mail]]]

mconnor suggested asking Kevin and Stephen for UI questions.  

Comment 8

[Ian Tommins ('thelem')]

At the moment we use the exclaimation mark in a yellow triangle, but surely a
cross makes more sense when something hasn't loaded properly?

Comment 9

[Christian :Biesinger (don't email me, ping me on IRC)]

at the moment we use no favicon at all

Comment 10

[Ian Tommins ('thelem')]

Sorry, I was referring to the modal dialog which is currently the default way of
showing these errors.

Comment 11

[Kevin Gerich]

Please use this image if you need something right away:
http://lxr.mozilla.org/mozilla/source/toolkit/themes/winstripe/global/icons/notfound.png

Comment 12

[Wolf [:wolf]]

My personal pick is either the Red Circle w/ X from the URL, or the img from
Comment #11.

Though, is a Red Triangle with an ! platform convention anywhere for an "error"
state?

Comment 13

[Mike Pesce (:By-Tor)]

I have to agree, the circle with the X just looks better.

Comment 15

[Henrik Skupin [:whimboo][⌚️UTC+2]]

We have to reopen this bug because favicons won't be included within the patch
on bug 280190. The work on that should be done in this bug when bug 301119 is
fixed. Currently loading of favicons from a chrome URI isn't allowed.

Patch to use the favicon within netError.xhtml. This will be checked-in after
the fix of bug 301119.

Attachment: Latest favicon from Kevin

Neil, are you willed to use the same favicon for the SeaMonkey part?

Comment 19

[Henrik Skupin [:whimboo][⌚️UTC+2]]

CSS styles already exist for each theme in themes/ and toolkit/themes. We only
have to put warning-small.png into Toolkit (pinstripe, winstripe, qute) and
SeaMonkey (classic, modern) folders.

They're a bad match. I only wanted to explain what things have to done during
the check-in.

Comment 25

[Mike Connor [:mconnor]]

Attachment: generic icon from Kevin

Going to add this as a resource: URI that can be accessed from the error pages,
and figure out what to do about making this skinnable in 2.0

Comment 26

[Mike Connor [:mconnor]]

Attachment: add data: URI favicon

ok, so error pages can't get to resource: URIs either.	There was apparently a
concern that this would clobber the bookmark favicon, but I had no issues in
Firefox testing.  SeaMonkey should do their own testing if this breaks their
bookmarks code (though I can't imagine why)

add data: URI favicon

ok, the seamonkey bookmarks code can use document.documentURI to figure out
which url to set the icon for.

1. "shortcut" is a Microsoftism, "icon" suffices.
2. Please use a binary encoding for binaries.
3. That particular image appears to have an artefact on it, and is also not
256-colour safe.
4. Please update line 320 of navigator.js as per biesi's comment.

OK, it transpires that the artefact gets hidden by the alpha transparency.

this addresses all but the 256 color-safe issue, which is an edge case

Actually you need
var url = content.document.documentURI;

[Mike Connor [:mconnor]]

Fixed, branch and trunk.

Comment 33

[Christian :Biesinger (don't email me, ping me on IRC)]

mconnor, it doesn't look like you checked in the navigator.js change...

Comment 34

[Alfred Kayser]

Instead of the "data:image/png, etc" url, one could also use:
   chrome://global/skin/icons/Warning.png
which is an allready existing icon in the current firefox theme, and also
refered to directly from the toolkit somewhere.
(if chrome access is allowed, see bug 301119)

Currently there is no way to set a favicon using a CSS rule
(may be something like : "body { icon: url("icon.png"); }" ??)
