I’d like to propose a feature that would greatly enhance reading and learning experiences in Firefox: a contextual hover dictionary.

Concept

When reading a webpage or PDF in Firefox, users often encounter unfamiliar words. Currently, this requires switching tabs and searching externally. Instead, Firefox could offer a built‑in dictionary overlay:

• Trigger: Selecting or hovering over a word prompts a small AI/star icon.

• Dictionary Card: Clicking the icon opens a compact card (similar to Google’s knowledge panel) showing:

  • Definition

  • Example sentences

  • Pronunciation (with a speaker button for audio)

Customization

• Source Selection: Users can choose their preferred dictionary provider (Oxford, Cambridge, Vocabulary.com, Dictionary.com, etc.).

• Style Options: Minimal vs. detailed card layouts, dark/light theme integration.

• Learning Mode: Option to save words into a personal “Word Bank” for later review, synced across devices.

Advanced Features

• Offline Cache: Frequently looked‑up words stored locally for instant access.

• AI Assistance: Simplified explanations or mnemonics for easier recall (e.g., “ephemeral = like Snapchat stories”).

• Cross‑Platform Sync: Word bank and settings available on Firefox desktop and mobile.

Benefits

• Eliminates the need to switch tabs for definitions.

• Supports students, researchers, and casual readers with instant clarity.

• Reinforces Firefox’s identity as a user‑centric, learning‑friendly browser.

This feature would transform Firefox into not just a browsing tool, but a personalized vocabulary companion.

Thank you for considering this idea.

Best regards,

Jaspreet
