rainbow-toolbar od Aria

Rainbow Bar replaces Firefox's single-row bookmarks bar with a customizable multi-row toolbar that shows all your bookmarks at once — no overflow menus, no hunting through subfolders.

What it does
- Reads your existing bookmarks from Firefox's Bookmarks Toolbar folder
- Displays them in a fixed bar at the top of every page you visit
- Adds new rows automatically when bookmarks don't fit in one line
- Updates instantly when you add, remove, or reorder bookmarks in Firefox

Features
- Multi-row display — grows and shrinks automatically as needed
- Gradient or solid color bar — choose any two hex colors
- Custom text color, font size, icon size, and item spacing
- Favicons loaded via DuckDuckGo (privacy-respecting) with Google as fallback
- Bookmark separators — create visual groups within the bar
- 8 languages: English, Español, 中文, हिन्दी, العربية, Português, Français, Русский

Privacy
No data is collected. No accounts required. No telemetry. All settings are stored locally in your browser. Favicons are fetched directly by your browser from DuckDuckGo.
