SideURL автор René Cotton

SideURL allows you to display any website in Firefox's native sidebar with complete customization options.

Features:
• Display any URL in the sidebar
• Automatic URL normalization (adds https:// when needed)
• Three icon options: automatic favicon, 16 preset emoji icons, or custom image URL
• Multilingual support (English and French)
• Privacy-focused: no data collection, all settings stored locally
• Clean and modern user interface

Perfect for keeping your favorite websites, tools, or dashboards accessible in the sidebar while browsing.

The extension is lightweight, open-source, and respects your privacy. All your preferences are stored locally on your device.
