This browser add-on is extremely useful as it allows you to switch a page between Traditional and Simplified Chinese so it can be used, for example, to convert a Chinese Wikipedia page into simplified characters. Pages you save will be kept in the writing system you have switched them into. Versions of New Tong Wen Tang exist for Chrome (linked to above), and also Firefox, Opera and Safari.
This is another browser add-on, which gives translations for characters and character combinations as you hover over them. Although Perapera is one of many add-ons that will do this for you, what is different about it is that it permits you to make a list of new characters as you go along; this list can then be exported and saved, for example in Word. Versions are available for Firefox and Chrome. NB By using this add-on on the pages of this wiki you can effectively use Bridge to China to study Chinese in the traditional variant, if that is what you want. (Please note though that this method may not be 100% watertight.)
