You're right that the built-in feature is "all or nothing" and doesn't provide fine control at all.

It sounds as though you do not want to alter the background colors, but there is a relationship: ending up with black-on-black is going to be unreadable. Is the main text color the key issue or is it the visited/unvisited link colors?

I think volunteers can provide some suggestions for configuration tweaks or add-ons if you can spell out in more detail what you'd like to see. Please include the text color you'd like to use.

Those font and color settings part of the are accessibility settings to improve the readability.

You would need CSS code in userContent.css or use an extension like Stylish to override web page colors in specific situations.

The customization files userChrome.css (interface) and userContent.css (websites) are located in the chrome folder in the user profile folder.

Thank you for the reply.

>>ending up with black-on-black is going to be unreadable<<

Yes, I know that. The font I set is black and the background is white. The black on black appearance is much easier for me to be realized or if I suspect that some words are hidden, I could make selection to see them. But I can not always do that with the other missing elements of the page such as image. You can even proof it when you write your reply in this forum; you can not see those icons bold, italic, bullet, etc. since they are considered as the page colors.

Thank you.

Thank you.

Do I have to have any skill of writing code or something ? If I have to, then I will give up. I know nothing about coding. I will visit the links you provided.

Thank you.

Hi dopadapo, CSS style rules run the gamut from simple to complex. The tricky part is not setting the color. For example:

body, div, article, section, p, span, li, th, td, input {color: black !important;}

The trickier part is finding a good solution for all the little exceptions that might arise... You might just give that a try for now and see what you think. cor-el's links describe where to introduce that rule, then you can restart Firefox and see whether it works for you.

It is best to avoid using the !important; as less as possible and only use it to override a style rule at the same level (test if it works and if it doesn't work add !important;)

On this forum you can use this for the reply text in userContent.css (works in the KB as well):

@-moz-document domain(support.mozilla.org) {
 body { color:#000 !important; }
 .container_12 .grid_9 { color:#000; }
 .container_12 .grid_9 .main-content a { color:#24f!important; font-weight:bold; }
}

Halo, jscher2000 and cor-el .

I have told you both, I am super Stupid :( concerning with coding or something like that.

Could you please write the lines (CSS style rules) that I can copy and use ? Please ?

1. The style can be used for any site I visit. 2. That style should make all texts black, all background white, but it keeps any image and other elements in their original colours.

Later, I will learn how to modify the style.

Thank you so much and sorry for taking much of your time. .

Easiest to achieve this would be to use the NoSquint extension.

You can use the NoSquint extension to set font size (text/page zoom) and text color on web pages.

Thank you, cor-el.

You know, I started looking inside that css file rather seriously yesterday :) and tried modifying them, but my stupid brain kept on telling me "why do I feel like making html file years ago before FrontPage appeared?" Then I downloaded an addon; a theme management or something that included css manager, but still I found it rather complicated. So, I stopped.

I have downloded the addon that the link you provided above and have set it as I wish. I like it so far. I can even set zoom level.

Thank you so much, both of you.
