Download DictionarySearch – Fast Firefox Context Lookup

Overview

DictionarySearch is a lightweight Firefox add‑on that transforms the browser’s right‑click menu into a powerful, one‑click lookup tool. Instead of the traditional copy‑and‑paste routine, users can simply highlight a word or phrase, right‑click, and choose from a list of customizable search engines. While the default target is The Free Dictionary, the extension lets you add any web‑based resource – from bilingual translation sites to specialized glossaries and even generic search boxes.

This flexibility makes DictionarySearch more than just a dictionary helper; it becomes a universal “search‑anywhere” companion that fits seamlessly into daily browsing. Designed for speed, the add‑on operates without adding noticeable latency, keeping Firefox’s performance intact. Whether you’re a student researching terminology, a multilingual professional needing quick translations, or a casual reader looking up obscure references, DictionarySearch streamlines the process to a single, intuitive step.

The add‑on is free, regularly updated for compatibility with the latest Firefox releases, and respects user privacy by performing searches directly on the selected service without storing your queries. In short, it maximizes Firefox’s built‑in search power while eliminating the friction of manual copying.

Installation, Usage & Compatibility

Installing DictionarySearch is straightforward. Open Firefox, navigate to the DictionarySearch page on Mozilla Add‑Ons, and click the “Add to Firefox” button. After granting the required permissions, the add‑on appears as a small icon next to the address bar. No reboot or additional software is needed.

To use the tool, simply highlight any word or phrase on a webpage, right‑click, and select “Search with DictionarySearch.” A submenu will display the default dictionary and any custom services you have configured. Clicking an entry opens a new tab (or the current tab, based on your preferences) with the search results from the chosen site. The configuration page can be accessed via the add‑on’s icon → Options. Here you can add new services by pasting a URL that includes the {query} placeholder, for example:

https://www.wordreference.com/enfr/{query}

Save the entry, and it instantly appears in the right‑click menu. The process is designed to be user‑friendly, even for those without technical expertise.

Compatibility: DictionarySearch is built exclusively for the desktop version of Firefox on Windows, macOS, and Linux. It supports Firefox 78 and newer, including the latest Quantum releases. Mobile Firefox does not currently support add‑ons, so the extension is unavailable on Android or iOS browsers. The add‑on adheres to Mozilla’s WebExtension API, ensuring smooth updates whenever Firefox releases a new version.

Pricing: The extension is offered free of charge. In the structured data below, the offers object reflects a price of 0 USD, making it clear to search engines that users can download and use DictionarySearch without any cost.

FAQ & Conclusion

Can I add my own private search engine?

Yes. In the Options page, click “Add New Service,” paste the URL that contains the {query} placeholder, give it a name, and save. The new entry will appear in the context menu.

Will DictionarySearch slow down my browsing?

No. The add‑on is lightweight and only activates when you right‑click a highlighted term, so it has negligible impact on page load times or overall performance.

Is my search data stored or tracked?

DictionarySearch does not log or store any queries. It simply redirects the browser to the selected service, which handles the request in the usual way.

Can I use the extension on Firefox ESR?

Yes. The add‑on is compatible with Firefox ESR 78+ as long as the underlying WebExtension APIs are present.

What should I do if a custom service stops working?

Check the service’s URL format. If the site changed its query parameter, update the URL in DictionarySearch’s Options page accordingly. You can also remove the entry and add a new one.
