Firefox **Click on the 繁 and 簡 to convert webpages, and the “S” and “T” to convert the clipboard.
Chrome/Chromium **Click on the 同文 icon to toggle between Simplified and Traditional, right-click for more options.
Safari **I have no experience with this browser, if you have tried it please let me know how to use it and I will update the post.
All other browsers **Drag the 繁 and 簡 characters into your bookmarklets (tabs), then click on either one when on a webpage to convert it.
SPECIAL NOTE: As with all automatic converters, New Tong Wen Tang is not without fault. With characters that have multiple conversions, such as 斗 in SC, is both 斗 and 鬥 in TC, I believe it either uses the most common version or it has specific vocabulary in its database.
Either way you should learn these characters by heart, as you will encounter this problem all over the Internet. You can find a very complete list of these characters, here, 簡繁一對多.
