more options

Hello. How could I change the color of the blue line over the tab? Could I hide it? It's too constranting and draws too much attention, that's why i want to hide it.

Chosen solution

The stripe on the "active" tab? You can hide that using a custom style rule. You can apply custom style rules to Firefox by creating a userChrome.css file. This takes five minutes to set up, ten if you watch the video.

This is the rule:

/* Hide blue stripe on active tab */
.tab-line[selected="true"] {
  opacity: 0 !important;
}
