Updated YammerFox plugin for FireFox v4

Yammer foolishly stopped supporting their YammerFox plugin after version 4 of FireFox got released leaving me with just the annoying desktop app or hideously bloated crapola like Yoono.

Some clever German chappy has now updated and released YammerFox for v4 and it’s as great as ever. Who knows if Yammer will let it continue so grab it while it’s hot!!
