Firefox is creating very high CPU use with many WebThumbnailExtension Web Connect processes. The processes disappear after shutting down Firefox and other programs that access the internet. Does anyone have an answer on how to prevent this from happening?

How is that a Firefox browser issue if that isn't a Mozilla itself? Maybe you should contact Apple about their extension issue if they are creators of it.
