I have Firefox 17.0.1 on Windows XP (SP3), on my EEE PC netbook.

My 1st problem is that I can't find the Cache folder. I can find it, if I type about:cache, and copy-paste, like that, but going through "My Computer," and otherwise manually navigating to it, I have problems. Why is this?

I've seen several pages (and videos) talking about finding YouTube videos, particularly in the Cache. Does Firefox's cache store Face Book videos, and if so, what file extension, and how can I find and view the videos?
