Question

I would like to control which parts in Stackoverflow are visible to me by a css file. There are about ten css -files in Firefox installation folder. I am not sure whether I should edit them or not.

How can I customize Stackoverflow by CSS in Firefox?

You can create a file called ‘userContent.css’ in your profile folder and it will be loaded on each page. Here’s more information: http://www.mozilla.org/unix/customizing.html

If you need to make changes which only affect one particular site instead of every site, then you can use this syntax:

@-moz-document domain(stackoverflow.com) {     body {         background-color:#f0f;     } }
