Does Fav. problem happen when you don't have Facebook page on? have you ever try that?
Besides, since crash happen again, could you help sending the crash report to us for analysis? The way to get MaxthonCrashData is as above.
Yes I think so, too. It's really an important bug which need to be fixed urgently because FB is such a popular platform nowadays.
Really thank you for your support and patience. It's really helpful for us.
