Very Useful Rated 5 out of 5 stars

This add-on is very useful! It lets me easily look up words in dictionaries, look up addresses in Google Maps, and translate text, among other possibilities.

This add-on's functionality is similar to the DictionarySearch add-on, but with some extra features, such as the option to open the results in a new window rather than a tab. It also uses a subfolders in the context menu, whereas DictionarySearch puts everything at the top level of the menu, which can make it cluttered.

Notes/Suggestions:
- If using the option to show results in a new window, any pipe symbols in the URL can cause a problem. So replace them by %7C.
For example, for Google Translate, use this URL:
http://translate.google.com/?hl=en&tab=wT#auto%7Cen%7C

- The selected text gets truncated, due to the add-on's use of the getBrowserSelection() function. Updating the code to instead use content.getSelection() avoids the text being truncated. I'm using Firefox 8, so I can't guarantee that function would work in earlier versions.
