You wrote the following in bug 1023889

MetaStream 3 Plugin reported Viewpoint Plugin vulnerable 3.2.2.26 "Update Now". When i clicked "update now" it went to a dead link http://www.viewpoint.com/technologies/viewpoint-media-player.shtml

I vaguely remembered reading someing on that plugin so I did a google search and found the following: https://addons.mozilla.org/en-US/firefox/blocked/p32 Viewpoint has been blocked for your protection. ...which links to: Bug 539282 - Blocklist the viewpoint plugin

I would remove (or disable) that plugin and uninstall the Viewpoint Media Player program from your computer based on the above and this wikipedia article:

• http://en.wikipedia.org/wiki/Viewpoint_Media_Player

/questions/753880 metastream 3 plugin 3.5.0.36 has been disabled due to security or stability issues, what do we do?

See also: /questions/976775 Why is Metastream plug-in listed when I do a Plug-in Check on what plugins are up to date, I thought it was blocked?

If it is blocklisted, shouldn't Firefox be flagging it up when it runs plugin check?

For example, I have a Java Development Toolkit plugin which flags up "Firefox has prevented the unsafe plugin '"Java Development Toolkit' from running on www.mozilla.org"

Having re-checked, this plugin is already disabled on my machine, but i think the bug report should still exist as it is still a false "update now" to a dead link.

richlaughlin, You asked, If it is blocklisted, shouldn't Firefox be flagging it up when it runs plugin check?

Good question but I think you should ask it in the PluginCheck bug you filed.
