RealPlayer plugins for Firefox question!

I only have Real Alternative installed but I see I have a "RealPlayer Version Plugin" and a "RealPlayer G2 LiveConnect Plugin". I suspect they are necessary but I figured I'd check here. Thank You!

I'd imagine Real Alternative would install browser plugins. However since I don't use it you'd either need verification from another user, or uninstall it to see if those plugins are removed. Reinstall it of course since that's what you use.
