Mozilla 4 Beta and 4Chan extension

I just installed Beta 4 and it works VERY well.  No bs.

Sadly, the extension made by DamageInc is broken and I am hoping it can be fixed/updated for 4.

the main error I get is:
TypeError: Components.classes['@4chan.wrathfilledhate.net/menu/manager-object;1'] is undefined

I have gotten a different one as well, but that is the biggie.

Any help?
