After it is installed, simply select and double-click on the word for which definition is needed. A small pop-up will appear listing the possible meaning of it.

As it is a dictionary look-up add-on, you can only select specific words and not entire sentences.

Clicking on the More option will open the definition in Google search.

 For older versions of Firefox:

One caveat when using Dictionary Anywhere in older Firefox versions like 62 and below is that you’d need to enable a setting for it. So for these versions, first type in the address bar:


Then in the search window that appears, copy-paste the following:

Click on the + sign next to it and set the value as true.

For all newer versions, these changes are not needed.

Trigger key:

Dictionary Anywhere by default will show a pop-up every time a word is selected and double-clicked. So you can use a trigger key for this. What this means is that only when this key is kept pressed and then the word is double-clicked, there will be the definition pop-up window and not otherwise like the default setting.

To set a trigger key, go to the add-on options by choosing Tools > Add-ons or typing in the address bar:


accessing Firefox add-ons options

Click on the Options tab. There will be different options available to configure from here.

From the Pop-up definitions section, assign a trigger key (either Shift or Alt).

Language and word history options:

Also, you can change the default language from here for the add-on. English is the default language but the add-on supports other languages like French, German and Spanish.
