[ubuntu] Adblock Plus in Quantal repository

view story

http://ubuntuforums.org – Normally I'm installing all Addons for Firefox manually but I thought I can use the package manager to do this. I know Adblock Plus was already available in some older versions of Ubuntu but I can't find it in Quantal. I have tried adblock-plus and xul-ext-adblock-plus but with no success. Was the package renamed or even removed? If it was removed what is the reason for this? (Hardware)
