FoxLingo may not be much to look at, but this free extension for Firefox comes with all the tools you'll need to translate a text selection or even entire Web pages.
The toolbar itself stretches across your browser window. The shortcut buttons aren't very attractive, but you can choose what buttons you want to appear on the toolbar, including flags that represent different languages. Each shortcut button lets you choose from a long list of languages for translation. The number of possible language translations with this toolbar is astounding. During our tests, we were able to translate an entire Web page very quickly. While we found a few words on the Web page that didn't translate, it certainly didn't keep us from being able to read the information. Likewise, we were able to select specific text for a quick translation. The Services shortcut provided us with myriad reference and translation tools. To use the AutoTrans feature, you have to utilize FoxLingo's search engine, but it immediately converted a Web page from French to English for us during our test.
All in all, FoxLingo is an extremely useful tool for both students and users of all skill levels.
