I guess my question to your post is; is that what caused me to not be able to download any videos?

I guess I am also wondering if this problem is caused by a bug in my system or if Youtube/Google caused it.

That’s what I need to find out. If I still have whatever caused the problem on my computer then I either need to find it a eradicate it, or reprogram it.

What’s your feeling?

Thanks for your help.

More than likely, your browser extension turned faulty as a result of YouTube updating its protocols to allow more efficient downloading of high-bandwidth video. Last May, a couple of Google engineers gave a talk on those changes.

So, you probably don't need to do anything except check for updated extensions. Or go for a non-browser solution, such as I outlined above.
