What Users Say

Frequently Asked Questions

Why doesn't the extension work immediately after installation?

After installing the extension, you need to refresh any pages that were already open in your browser. The extension only activates on pages loaded after installation.

Why doesn't the extension work on the Chrome Web Store, Edge Add-ons, or Firefox Add-ons pages?

For security reasons, browser extensions are not allowed to run on extension store pages such as the Chrome Web Store, Edge Add-ons, or Firefox Add-ons. This is a browser restriction and applies to all extensions.

Do I need to refresh pages after changing extension settings?

Yes, after changing most settings in the extension, you should refresh any open webpages for the changes to take effect. But on the options page itself, changes apply immediately without needing a refresh.

How can I add more dicts to my Dictionariez?

You can add more dictionaries from the Dictionariez Trove. Just click the Add to Dictionariez button next to any dictionary you want to add, and it will be added to your extension.

What if I find a free web dictionary that's not in the Dictionariez Trove?

If you discover a free online dictionary that isn't yet available in the Dictionariez Trove, you can help the community by submitting it! Just follow the instructions at How to add a new dictionary to the Trove .

What if my target language is not supported for double-click lookup?

Currently, the double-click functionality supports 20+ languages. If your target language is not in the list, please send me a feature request at the feedback forum. I’m happy to add more languages! For example, when a user requested Turkish support, I added it quickly: see the Turkish support request.

How can I look up words in PDF files?

For looking up words in PDFs, use the PDF Reader I made. It's free and completely privacy-focused: no content is uploaded anywhere. You can also select any text in the PDF to have it read aloud by Dictionariez.

How can I report bugs or issues?

If you find a bug, please don’t just walk away. Help me make Dictionariez better for everyone! By reporting issues, you’re also helping other users. You can report bugs or issues on the feedback forum. If you prefer GitHub, you can also open an issue at the Dictionariez GitHub Issues page.

How does Dictionariez handle my privacy?

We care deeply about your privacy. In general, Dictionariez does not collect any browser information or personal user data. Your lookup history and settings are stored locally in your browser's storage and synced using your browser's built-in sync service. For some pro features, only the minimal necessary text is sent to the server to provide the service, and all of these features can be turned off at any time. For a detailed breakdown, please see the full Privacy Policy.
