Why are videos imbedded in virtually all blog sites simply black rectangles that will not open and play?
I get no videos embedded in blogs or other pages. I get only black rectangles that won't open.

If you use extensions (Tools > Add-ons > Extension) like Adblock Plus or NoScript or Flash Block that can block content then make sure that such extensions aren't blocking content.
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.

In Firefox 4 Safe mode disables extensions and disables hardware acceleration.
- Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
If disabling hardware acceleration works then check if there is an update available for your graphics display driver.
