I also noticed that the ads you can skip do not work. with the same error message.

It maybe because your javascript is disabled . You can check the javascript.enabled pref on the about:config page.

There are also extensions that can block JavaScript or otherwise interfere.

Or, "Clear the Cache":

Firefox > Preferences > Advanced > Network > Cached Web Content: "Clear Now" "Remove Cookies" from sites causing problems:

Firefox > Preferences > Privacy > Cookies: "Show Cookies"

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

Do NOT click the Reset button on the Safe Mode start window.

please report us if any problem.

Tried all that with no luck. Its almost as if something is blocking only the videos in youtube.

Try installing a fresh installation of windows then install the latest Firefox . Hope this will help.

Can't install a fresh version. The restore partition was erased before I got the computer and it was upgraded from windows 8 so I am stuck with the iso image I have. Tried restarting with that iso image with no luck.

uninstall your firefox . delete all the folders and files from C:\Program Files\Mozilla Firefox and C:\Program Files\Mozilla Maintenance Service

restart you computer the download the latest version of mozilla .. download from this link , it will download a offline installer ftp://ftp.mozilla.org/pub/mozilla.org/firefox/releases/32.0.2/win32/en-US/Firefox Setup 32.0.2.exe

then install firefox again ..

Still no luck. After trying that I even went through and deleted every firefox entry in the registry then reinstalled and it did nothing to help.
