Cannot download Google Chrome

Hello, I tried very recently to download 'Google Chrome' and the other new browsers as 'You Tube' have announced that they will no longer support my old browser. Now, I don't know about you, but my old browser worked JUST FINE! and I had no problem in watching 'You Tube'. So, I tried to download Google Chrome, to no avail. I was told the application failed. I tried another (Firefox 35 I think) or something like that. After downloading the file and getting ready to kick off, I was told that there was an error and the file downloading could not be completed. Why we simply don't leave things alone I will never know. My old browser worked fine, but we've just got to continue to mess things about. I guess that it will be "goodbye" to 'You Tube' from me, because every modern browser that they have promoted, I have not yet been successful in downloading. How's that for modern technoligy?
