Last updated: 2026-10-16

Features & Capabilities

Look up a word without losing your place.

Double-click any word on any web page, or select a few words with the mouse, and a small popup appears with the definition, right where you are reading. Press on and the popup disappears when you click away.

FEATURES

Instant lookups: up to five definitions, with part of speech and example sentences where available.
Phrase lookups: select several words to define the whole phrase.
Pronunciation: a speaker button that reads the word aloud with your browser's text-to-speech, plus a phonetic transcription and a recorded pronunciation where available.
Search engine: choose Google or DuckDuckGo for lookups and the Learn more link.
Nested lookups: met another word you do not know inside a definition? Double-click that one too.
Trigger key: optionally require holding Ctrl, Alt or Shift (Command on macOS) while double-clicking or selecting, so popups only appear when you want them.
Word history: optionally keep the words you look up, see the count on the options page, and export the lot as CSV. It stays on your device.
Dark mode: the popup follows your system colour scheme.

PRIVACY

No accounts, no analytics, no tracking, and no data sent to the developer. The only thing that leaves your browser is the text you select to define, sent to the search engine you choose (Google or DuckDuckGo) and, if that finds nothing, to a dictionary service. Your word history is stored locally and never transmitted. Full policy: https://github.com/eldon922/define-select-dictionary/blob/main/PRIVACY.md

Definitions come from a web search for the selected text on your chosen search engine (Google by default, or DuckDuckGo), with the free Dictionary API (dictionaryapi.dev) as a fallback.

Open source under the GPLv3. Originally based on Lexigo by Jort van Leenen, itself based on Dictionary Anywhere by meetDeveloper.

Is Define Select Dictionary Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Define Select Dictionary requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Define Select Dictionary is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
