I’ve updated my MonstersGame extension — no version change, the current version works in Firefox 2.0.*, so all I did was bump up the maxVersion. When I get time, I will sit down and do a proper update to add the new MG features.
Download from the same places: (the Firefox/Mozilla site down at the time of this post, so if you don’t see an update note on the Addons site try the link here first!)
