About this Add-on
Lopburi is a province in Thailand.
For OSX Scrolling issue, I've known this for a long time (I have one iBook too) but this is something I can't figure out why it happens. I'll try my best.
FYI, Lopburi is the name of one province in Thailand.
Mac OS X users should see scrollbar now. (I haven't test on Mac yet).
#Editor can remove this
Thanks MozUpdate editor (I don't know the name) who reminds me about Filter Dialog. Thanks.
