videos from networks (abc, nbc, fox, etc won't play online anymore).
I can't get videos (like shows such as NCIS) from sites like Hulu, or abc.com, cbs.com, fox.com, etc. to play anymore. This just started a couple of days ago.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the Safe mode start window to disable all extensions.
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")
I did all this and it did not help.
I upgraded to Firefox 4.0. Comodo Firewall wanted my permission for my plug-in Container to connect to the internet. I am now watching video on abc.com. Don't really know if it was Firefox or Comodo. Either way it works now.
