How to increase the contrast of Firefox tabs
Apply this CSS somehow, for example through stylish:
.tabbrowser-tab .tab-label { opacity: 1 !important; color: black !important; background-color: white; } .tabbrowser-tab[pending], .alltabs-item[pending] { opacity: 1 !important; color: black !important; background-color: white; }
If you use Stylish add this namespace line first:
@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);
I used Firefox - style of inactive or unloaded tabs - Themes and Skins for Browser - userstyles.org as a template.
