1. PithHelmet 3.0 Beta
This is an early release that strives to make things simpler in the long run.
The main goals are compatibility with Snow Leopard and with the AdBlock Plus rule format.
1.1. Notable Differences
The Good
64-bit Safari compatible
Supports both Safari 4.0 and 5.0
Supports both Leopard (10.5) and Snow Leopard (10.6)
Supports both PPC and Intel
AdBlock Plus rule files "just work"
The Bad
GIF animation blocking doesn't work
Applying custom CSS is a bit buggy
Transmogrification isn't supported
Cookie blocking/filtering isn't implemented
The Ugly
There is no longer a preferences pane - everything is accessible from the menu.
The complicated rule editor has been removed. Rules can added with the "Show Blockable Items", but you currently have to edit rules manually in a simple text file.
