These ports are www. xpi-adblock contains Makefile.xpi with some comment. Many things are missing. If you think that it will do more harm than good to expose these to public, let's discuss improvements on ports@. I've tested these ports with firefox and linux-firefox (separately and simultaneously) - and they work fine. Creating and maintaining xpi- ports is really a breeze. Note though that the infrastructure does not implement XPInstall specs, it is only a little hack to make porting xpi's easier.
Responsible Changed From-To: freebsd-ports-bugs->thierry Take it.
State Changed From-To: open->closed New ports added, thanks! Remark: I have moved CATEGORIES from www/xpi-adblock/Makefile.xpi to each Makefile, in order to fix a fatal portlint error.
