Month & Week Picker for Firefox ავტორი Haris Wijayanto

Firefox is the only major browser that doesn't provide a built-in picker for <input type="month"> and <input type="week">, leaving users to type raw ISO values like "2026-02" or "2026-W07" manually.

This extension fixes that by adding clean, accessible picker popups that open when you click or focus on these inputs just like Chrome and Edge do natively.

Features:
• Month picker with a simple month grid and year navigation
• Week picker with a full calendar view and ISO week numbers
• Locale-aware display shows "February 2026" instead of "2026-02"
• Placeholder support for empty inputs
• Clear and "This month/week" shortcut buttons in the picker footer
• Respects disabled and readonly input states
• Adapts to your OS theme (light/dark mode and accent color) using CSS system colors
• Isolated styles via Shadow DOM won't break page layouts
• Works on all websites
• No data collection whatsoever
