Twinklelight for Mozilla Firefox is really a useful add-on that shows the possibility of translating a Tweet in English. You just have to click the button to appear next to the tweet.
This add-on is really lightweight and your browser will not notice it and you can get a tweet in a language which you can not understand is extremely useful.
Translation time only takes one or two seconds and you will be able to read the tweet as usual.
Twinslet is a perfect aliot for English speakers, which usually follows foreign users by speaking different languages ??like Japanese, Spanish or German.
