This started 2 days ago for me and haven't found a way to turn it off.

Thanks, that did the trick. Here's what I did.

1) Went into about:config and looked at the plugins.update.notifyUser listing and saw that it was already on False. I changed it to True and then back to False. Also, the URL that is below it, I deleted the URL.

2) Went into Windows Program Manager and uninstalled the Viewpoint Media Player.

3) Went back into FireFox and selected Tools and Addons and disabled the MetaStream 3 Plugin.

Restarted the PC, and now it's back to normal where it open opens one tab with the about:blank.
