Foreign Language Translation Browser Apps and Extensions

We all have our favorite websites, those go-to destinations where we take our browser on a regular basis. In addition to the usual stops, many Web surfers will also do some exploring from time to time, catching the next wave to sites they've never visited before. Some of this searching may be targeted, while at other times we may just stumble around until we find something cool.

While it may seem like the number of Web pages available to us is limitless, just imagine how that figure would rise if you included all of the non-English sites out there. The abundance of content presented in languages other than our own is staggering, and there are plenty of free browser apps and extensions that provide translations, definitions, and other dialect-related assistance so we can truly take advantage of the World Wide Web's global presence.

We've listed some of the best below, available for Chrome and Firefox and sorted alphabetically.
