Dictionary Everywhere

New! Dictionary Everywhere brings back instant word definitions to every page you read. Just double-click a word and a clean popup shows you its meanings, grouped by part of speech. No new tabs, no copy-pasting into search engines or AI chatbots.

Features:

• Instant definitions: Double-click any word to view concise definitions directly on the page. Dismiss with Esc button, by clicking the x, or by clicking anywhere else on the page.
• Structured meaning: Full definitions, grouped by part of speech. Reliable and accurate.
• Lightweight & Private: No accounts, no analytics, or background tracking.
• Open & non-profit: Powered by Wiktionary from the Wikimedia Foundation, the non-profit organization behind Wikipedia.

Important Note:

• Dictionary Everywhere can't run on pages that restrict add-ons (such as about:debugging, built-in PDF viewer, or Reader View). This limitation applies to all extensions of Firefox.
• The add-on is designed for desktop use with a mouse or trackpad that can double-click.

Privacy & Data Transparency: Dictionary Everywhere collects zero personal data, browsing history, or analytics. The only data transmitted is the single word the user double-clicks, which is sent directly to the official Wiktionary API to fetch definitions.
