When I try to access the xfinity tv option from the comcast home page, I am directed to the page where the player should start. The player never loads and no matter which program I select to play, nothing happens. If I do the exact same thing using IE, the player starts and the show I selected plays. The url is an example of what does not work. I am running 3.6.10 firefox Windows XP SP3

That is Flash content.
You have the latest Flash player (10.1 r85) so Flash should work.

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")
