I was able to make use of YouTube with this extension until just recently when it suddnely stopped working and I really need to be able to view donwloaded videos offline as some places in my house get no internet commections and one is the best for watching videos.
I'm also stuck using Firefox v39 as later versions just didn't work or at best were highly unstable on Windows 7.
