Although that I this is a very interesting extension and can be a time saver to many text writing users on the web, I gave only 3 stars because it can ONLY replace text and symbols in the text box of "Google translate" website only. It doesn't work on any other website, or Addon/extension which have full/or pop up text page input window. Fix this problem (to be able to replace text everywhere), and I will give 5 stars on my rating.
