Ghost Tabs

A Zen Browser mod that makes unloaded tabs & folders appear ghost-like. Now fully customizable with saturation and transparency controls.

The goal is to make them easier to distinguish from loaded tabs, while still being visible enough to identify them.

Inspired by Felkazz/zen-browser-better-unloaded-tabs, which at the time of writing was no longer maintained.

Customization

You can customize the appearance of Ghost Tabs via the Zen Mods settings page:

• Saturation (0-100): Adjust how much color the ghosted tabs retain (0 is fully black & white).
• Opacity (0-100): Adjust the transparency level of the ghosted tabs.
• Enable Black & White effect: A quick toggle to enable/disable the grayscale filter entirely.

How it works

This mod makes the following elements appear "ghost-like" (grayscale and semi-transparent):

• Unloaded tabs: Tabs that are not currently active appear ghosted to distinguish them from loaded content
• Folders with only unloaded tabs: When a folder contains exclusively unloaded tabs, the folder itself appears ghosted
• Exclusions: Folders being renamed (name editing) remain fully visible for usability
