How to Quickly Define Any Word on a Web Page [Firefox]

How many times have you come across a word online that you’ve never heard of before? How many times have you come across a word you have heard of, but just didn’t know the meaning? Either way, you’re left in the dark ┬ábecause you have no clue what you’ve just read.

The easiest way to resolve this issue, while using Firefox, is to install the WikiLook add-on. With it, you can lookup and define any words that you want. Plus, it supports over 70 languages, so you can look up foreign words as well.

Here’s how:

1. Install the WikiLook add-on for Firefox and be sure to restart your browser.

2. While browsing the Web, use your preferred method of defining a word.

  • Hold down Shift while right-clicking a word
  • Hold down Ctrl (or Command on Mac) while right clicking a word
  • Hold down Alt (or Option on Mac) while right clicking a word
  • Highlight a word, right-click on it, and select “WikiLook” from the menu

Note: You can enable/disable your preferred methods in WikiLook’s Options, which can be accessed from the Add-ons Manager in Firefox.

View word definitions and hear pronunciations in Firefox.

3. Upon activating WikiLook, the definition of the word will display right on the page in a popup (as seen in the screenshot above). If you have the option enabled, you’ll also hear the word being pronounced on your computer.

Now you can find out what any word means in a matter of seconds. If you want to turn WikiLook off, just click on the fancy green “A” icon on the Firefox Add-on Bar.
