pluginManager.js error

[chenxsan]

Hi,

I'm trying pluginManger.js on firefox 20 with vimperator 3.7 but got error as the screenshot showed below.

I tried to set up a all new firefox profile with -no-remote -P command, and installed only vimperator 3.7, when loading scripts the error was still there.

My OS is Ubuntu with enlightenment 17, and pluginManger.js file was downloaded from branch 3.6.
