Targeting mozilla firefox Browser

[comfre]

Hey guys,
I want to adress a special css code just to the mozilla firefox browser. I found this command on the internet:

@-moz-document url-prefix() {
.csscategory{
code;
}
}

Where do I have to paste it to?

Hello @comfre,

Thanks for asking.

You can add the CSS code under X > Theme Options > CSS. Here’s a screencast that you can take a look.

For Firefox specific CSS, you can also refer following article:
