I uninstalled Viewpoint Media Player (and the AOL IM client "AIM", since apparently that's what forced Viewpoint Media Player on to my system.)

Viewpoint Media Player is responsible for the plugin called "MetaStream 3 Plugin r4", and I believe this plugin is triggering Firefox to open the plugincheck page. It is not enough to disable the plugin, it must be uninstalled.

For me, after uninstalling Viewpoint Media Player, the "plugincheck always opening" problem then went away.

I started using Fire Fox to get away from this crap. I consider this forced plug in thing to be a tracking Trojan and pop up adds. It's my opinion this has become no different than I.E. or any other Micro Soft application where I loose control of how I manage my own computer applications by having things forced on me that I necessarily don't want. I plan to quit using Fire Fox until I am assured this doesn't happen any more and and feel confident my browsing and other web activity is not being monitored and tracked by Mozilla. What other data and applications can we assume they are looking at on our computers? I think if this is the direction they are now headed, other folks should do the same thing.

That is a bug with blocklisting plugins that has been fixed.
You can correct this issue by forcing the file blocklist.xml to update or wait until Firefox updates the file.
That update will remove the severity="0" flags in the file that cause the problem.
