turning off color and background-color bug ?

aurelien.levy@gmail.com
Hi,

I have a question about a Firefox behaviour, for my it's an
accessibility bug but maybe i am wrong.

When the user turn off the color in his preference, all the element
with absolute positioning and a background color become transparent
instead of inheriting the root element background color or the default
system background color.

A practical example can be the dropdown menu, when i turn off the
color, the background of the menu become transparent and his content
become unreadable because it overlay the page content (for example
look at the quick contact feature in gmail or the status choice with
dropdown). I know we can correct this by css hacking with background
iframe (look at the "more" menu in gmail) or image (an img element
with white background with the height and width and the menu and
positioned under the menu with z-index and absolute positioning) but
this is really awful techniques.

Is there any chance to correct this in Firefox ?

(For information I have not this problem with IE)

I haven't looked at it too closely, but what do you mean by "When the
user turn off the color in his preference"?  I know how to prevent a
page from overriding my colors.  I know how to override system colors
with Firefox settings.  I don't know how to turn colors off.  Can you be
more specific about what setting you are changing?

I'm sure others know, but I just haven't played with the color settings
enough.

Tom

aloha, aurelien!

i don't know about native firefox support for turning off color
and background color posing a problem, but i do know that you can
easily change them using either the FireFox Accessibility Extension
(FAE), available from:

http://cita.disability.uiuc.edu/software/mozilla/

or the accessibar plugin, available from:

https://addons.mozilla.org/en-US/firefox/addon/4242

hope this helps, or, at least, enhances your browsing experience,
gregory.

Yes sorry, I mean when the user select the option to prevent a page
from overriding his colors preferences (I say turning off color
because I activate this option with the webdevelopper toolbar where it
call like that.)

aloha, aurelien -- let me take another try at helping you reset FF to
reflect your designated color schemes and to override author-provided
styling:

1. from the Tools menu, choose Options

2. when the Options dialog appears, select the "Content" tab

3. there is a fieldset in the dialog whose legend is "Fonts and Colors"

4. if you select the "Advanced" button in the "Fonts and Colors" property
   sheet, you should be able to tailor the fonts, and by DISABLING the
   last checkbox on the "Fonts and Colors" property sheet, "Allow pages
   to choose their own fonts instead of my selections above" -- this
   checkbox is checked by default, so make sure you uncheck it;

5. when you are done with setting font families and sizes, activate the
   "OK" button, which will bring you back to the "Content" tab;

6. find the "Colors" button (it is in the "Fonts and Colors" fieldset),
   and activate it -- this will spawn a property sheet dialog named
   "Colors"

7. in the "Colors" dialog, you can:

   * set background and text colors
   * set FF to use system colors (respect system's settings)
   * set link colors and whether to underline them or not
   * uncheck the checkbox "Allow pages to choose their own colors,
     instead of my selections, above" (again, i believe this checkbox
     is checked by default

that should allow you to keep your system settings and/or user-defined
settings for FF

additionally, from the menu, if you choose "View", then "Page Style",
then "no style" - it should disable stylesheets in FF, leaving you with
FF's default style rules)

hope this helps, gregory.

Thanks Gregory but my problem is not to use my own color or background-
color or to use Firefox preferences or anything else to do that.
Actually, I don't need myself to to that. I just send a comment about
what I think is a bug in Firefox.

I think that element must inherit the root element background color or
the system default background color instead of becoming transparent
otherwise there is some problems off overlaying and unreadable content

I posted a respond, but I don't see it.  Maybe it didn't like the
attachments I added, so I'll repeat.

I agree that this is a Firefox bug.  When I disable a page's ability to
specify its own colors, all of the elements have their CSS
background-color set to "transparent" rather than to the color I've
specified.  This is a fine optimization if there is no overlapping
content, but as you've pointed out, that's a naive assumption.

Yes that's exactly what I am thinking too.

I will be happy if Aaron can give is opinion about that.

Is there a need to fill a bug for that in buzilla ?
