Use the extensions (must install both), then when you open a VIP chapter to read (must be on Desktop interface), wait about less than 1 minute, the Graphic user interface of Faloo web page will change, and the Chapter will be tranferred to sangtacviet automatically. After that, read the new faloo chapters on sangtacviet. Sometimes, you have to click update 'cập nhật chương' for new chapters to show up.
I don't know why you keep speaking ENGLISH in a VIETNAMESE forum (google page translation?). Most people would understand but it was really annoying. In fact, We really welcome you to join us. So, please use a translation tool or something else to input the vietnamese text in the future.
One last thing, please be careful. I just had my faloo Star VIP account banned (>$100 US dollars are gone forever). The admin also had the same problem. I highly doubt that the reason for this, is NOT buying all the chapters of a novel (Like I bought chapters 500-700)
