There's no need to do anything except restart the browser once or maybe twice. There's already a patterns.ini file in there that works perfectly fine for me and many others, which is how it got into extras to begin with.
Microb has some sort of bug in it that causes plugins to not immediately be recognized and it goes back to Nokia's official versions of these plugins that were released for OS2008. That's why the browser restart is needed, but for some reason, it doesn't always take right away. This isn't my fault and there's nothing I can do about it.
Other than that, the plugin works and has always worked fine for me and most of the community.
The person that posted that it was not optified made a mistake and wanted to take back what he said as you can see in his comments.
As far as I'm concerned, there aren't any blockers with the package. Even Andre, Tim and other big names in the community thumbed it up and if anyone is going to catch any real issues, it's those guys.
By the way, if you want to know why there isn't a section for Adblock in Bugzilla, it's because I was told no when I asked.
I'd like to go back to working on it, but since my N900 is broken and I still haven't received a response from Nokia...
