Today, I launched my very first add-on for Mozilla Firefox: Multi Dictionary Lookup.
Why did I create Multi Dictionary Lookup?
I created this add-on because I felt the need for a dictionary plug-in that lets me look up the definition of a word without leaving the page that I am reading. A simple right click on the highlighted word brings up a choice of dictionaries with which to look up the word.
New words constantly appear in the English language, and such words may not be present in the official English dictionary. For such words, I consult the Urban Dictionary.
For some words, it helps to know the synonym and antonym, along with sample usage in a sentence. For such words, I consult the Bee Dictionary.
For the rest, the Free Dictionary is the best!
