Firefox color theme almost works

[Toxikuu]

I'm using the firefox theme option in sidebery's settings. I'd like to replace the gross grey (seen in the top and right border) with my gross blue. How might I do that?

I tried setting the border variable with the styles editor, but it didn't appear to change anything. Though, for what it's worth, I saw none of my styles editor changes reflected.

#sidebar-header {
background: gross blue !important;
}

Put it in userChrome.css

If you don't know what that is. There's instructions here.

Thank you! That fixed the header. Although it didn't fix the right border, the hint about userChrome.css was enough for me to find the solution for that.

If anyone finds this later, the css selector for the border is #sidebar-splitter. The following links may be of use:
