Being a non-native English speaker, I have this mildly often need to lookup the translation of some word in the dictionary. Instead of installing translation software on my computer or visiting one of the online translators every time such a need arises, I chose to use an extension to Mozilla Firefox.
Until now I was using the DictionarySearch extension, which can be configured to lookup in several different dictionaries, encyclopedias, etc. I was mostly happy with the extension, but felt that it could be improved simplified. I didn’t need all those configurations, choices and such. All I wanted was to lookup the translation of either English or Russian word in the Yandex Lingvo.
Today I came across an extension which does exactly that. Lingvo Online! for Mozilla Firefox is a very small and simple extension which does exactly what I want. It adds a context menu which allows quick lookups of selected words.
Outstanding!
