This addon tool help you with translation issues.
The official website tell us :
“Dictionary Anywhere” provides access to a floating multilingual Google Translate panel on any webpage. This add-on injects an ifram containing Google Translate only when a translation is requested. To request a translation, select a word or phrase and then click on the bubble that appears on top of the selection area. Using this extension you can get in-page translation as well as pronunciation. At the bottom of the iframe, there are two links to open the desktop version of Google Translate and Google Search prefixed with ‘define’ keyboard.
This addon can be used with firefox , chrome, and opera browser.
